CryoSPARC v4.4

November 8, 2023

We’re excited to announce another release of CryoSPARC! Version 4.4 includes Workflows and Blueprints, Reference Based Motion Correction, new tools for orientation diagnostics, many feature updates, performance optimizations and various stability enhancements.

New

CryoSPARC now bundles CUDA Toolkit 11.8; a separate CUDA Toolkit installation no is longer required by the CryoSPARC worker application.
BREAKING: CryoSPARC v4.4 requires NVIDIA driver version 520.61.05 or newer.

New

Introducing Workflows and Blueprints:

  • Workflows: Workflows make it easy to replicate processing that you’ve done before. Select a chain of jobs to create a templated processing Workflow, and re-create it in any project or workspace with a single click. Annotate the Workflow with a description and tags, set up default or locked parameter choices, and easily share Workflows from one CryoSPARC instance to another.
    Creating and applying workflows
    • Workflows are flexible. You can create a linear Workflow that for example, starts with an import job and proceeds all the way to a refinement, to make it easier to process a new dataset using an existing set of steps. Alternatively, you can select a portion of a processing workflow that you would like to re-use for exploratory processing (e.g., for sorting particles or separating heterogeneity).
    • Use Workflows to save time, to maintain consistency and repeatability, and to capture important target-specific or facility-specific processing details and patterns so that new users can get a head start.
    • Watch a tutorial video and read the in-depth Workflows guide to get started.
  • Blueprints: Blueprints allow you to define custom parameters and annotations as a template for any job type. Apply the Blueprint to an existing job or create a new job from a Blueprint directly from the job builder, in any workspace or project.
    Creating blueprints
    • Save time and avoid mistakes in entering parameter values by creating Blueprints for e.g., import jobs for specific microscope setups, classification and refinement jobs for specific protein types or sizes, settings for specific computational configurations, etc.
    • Create Blueprints to avoid searching across projects for the parameters of previous runs of a particular job type. Easily export, share, and import Blueprints from one CryoSPARC instance to another.
    • Read the in-depth Blueprints guide to get started.
New

Reference Based Motion Correction (BETA) in CryoSPARC improves final resolution and map quality by re-estimating per-particle motion trajectories using a reference volume, similar to Bayesian Polishing (Zivanov et al, 2019).

New

Orientation Diagnostics, a job that rapidly computes a set of easily interpretable diagnostics to identify orientation bias and anisotropic signal content in 3D refinement results. Quickly identify potential data collection, sample preparation, or particle picking/curation issues with two complementary statistics: Conical FSC Area Ratio (cFAR), sensitive to anisotropy in signal content and alignments and Sampling Compensation Factor (SCF*), sensitive to anisotropy in alignments (Baldwin and Lyumkis, 2020).

New

Non-Uniform Refinement is up to 2x faster: the core computation for non-uniform cross-validation regularization is optimized on GPU to be 7x-10x faster. This translates to approximately 2x faster overall run time for Non-Uniform refinement jobs, and Helical and Local Refinement jobs with non-uniform regularization enabled.

Non-uniform refinement speedup
New

3D Flex Reconstruction job now supports CTF aberrations during high-resolution reconstruction. Also, there is now an option to read particles from SSD cache or from project directories during reconstruction, rather than loading all particles into RAM. This option substantially decreases the CPU RAM requirements for reconstruction.

  • In addition, 3D Flex dependencies are now bundled with CryoSPARC and no longer require a separate online installation step. 3D Flex now supports the latest NVIDIA GPU compute capabilities 8.9 and 9.0.
New

Symmetry Relaxation: There is now an option to relax the pose search over symmetry-related views in Homogeneous and Non-Uniform Refinement.

  • A “break symmetry” option is available in Homogeneous Reconstruction that randomizes particle poses over the chosen symmetry group.

    Symmetry relaxation
New
float16 Support: Particles and motion-corrected micrographs can now be output in 16-bit floating point format, via a new parameter in motion correction and extraction jobs. This can cut disk usage in half for large projects. The option to output float16 can also be set as a project-level default parameter.
New

AFIS Beam Shift Import: In Import Movies and Import Micrographs, beam shift values for data collected in EPU via the Aberration-Free Image Shift (AFIS) method can now be directly imported, and exposure groups created based on clusters of beam shift values.

  • For existing exposure datasets in CryoSPARC, add beam shift information using the new Import Beam Shift job. In the Exposure Group Utilities job, cluster exposures into exposure groups based on imported beam shift values automatically.

    AFIS beam shift import
New
Regroup 3D job quickly creates a set of ‘superclasses’ from a larger set of upstream 3D Classification or Heterogeneous Refinement classes. It uses a lightweight spectral clustering algorithm that can aid in identifying dominant conformational variations.
New
Heterogeneous Reconstruction Only job reconstructs multiple classes from upstream 3D Classification, Heterogeneous Refinement, or Regroup 3D outputs. It uses weighted back-projection via upstream class posteriors, with an option to apply hard classification. It includes similar reconstruction options as the Homogeneous Reconstruct Only job (including symmetry, box size, etc.).
New

Viewing direction distribution plots now include an option to export as a BILD file for visualization in UCSF Chimera(X).

Viewing BILD files in ChimeraX
New

Experimental SSD cache system with significantly improved reliability and support for network drives. To enable, add export CRYOSPARC_IMPROVED_SSD_CACHE=true to cryosparc_worker/config.sh. See the guide for more details.

SSD caching
New

Improved behaviour of the Data Cleanup Tool to streamline compaction of projects and workspaces:

  • All options are unchecked by default.
  • When running the Cleanup Data tool on a single workspace within a project, jobs that are linked to other workspaces will no longer be deleted by the tool; instead those jobs will be unlinked from the workspace being cleaned and will remain present in the other workspaces.
  • CryoSPARC Live jobs, which are excluded from the cleanup process, are marked as “Skipped” and their size is now displayed.
  • The total project directory size is now displayed in the cleanup tool along with the total size of data that the tool can clear, which may be different due to imported and manually copied files that may be present in the project directory.

    Data cleanup tool
New
2D Classification implementation that reduces memory usage and provides speedups with larger datasets. The original implementation is available as a legacy job type.
New
Reconstruct 2D Classes job that reconstructs 2D class averages from previously classified particles.
New

Ability to set custom parameters within the Live session view when configuring custom Streaming 2D Classification, Ab-inito and Streaming Refinement jobs.

Data cleanup tool
New

Job cards now indicate warnings and errors, along with a text preview. If a job contains warnings or encountered an error, an icon will display in the cards and tree view. Hovering over the icon will display more information about the warning/error. A subset of the error will be visible directly on the job card view if applicable.

Warnings and errors displayed on the job card
New

Ability to copy parameter code name via the ‘Inputs and Parameters’ tab when previewing a job. This name can be used in cryosparc-tools scripts.

Copy parameter name from the job preview dialog
New

If a job exists in more than one workspace, an icon and informational tooltip will be show on the cards view. In addition, jobs that display in the tree view but are not explicitly linked to the selected workspace are marked with an icon and informational tooltip for additional context.

Linked jobs are marked with an icon on the job card
New

Ability to star a Live session from within the session view through the primary dropdown menu.

Star a session from the session menu
New

Import Particles contains a new set of parameters to enable build-time output group generation and validation. This allows Import Particles to be used within Workflows for automated processing.

Import particles build-time output groups
New

Update

The Validation (FSC) job now outputs an additional FSC figure with square plot markers along with a line, to more clearly see each resolution shell.

New FSC validation marker plot
Update

CryoSPARC v4.3

August 9, 2023

We’re excited to announce another release of CryoSPARC! Version 4.3 includes new tools for data management, performance benchmark utilities, improvements to interactive jobs, many feature updates, performance optimizations and various stability enhancements.

New
Data Cleanup Tools
  • A new suite of tools to simplify the process of tracking and reducing disk space usage in CryoSPARC. Supporting five ways to clear up projects or workspaces:
    • Mark certain jobs as final and automatically clear everything except for jobs needed to replicate those results
    • Compact CryoSPARC Live sessions, removing preprocessing data but storing particle locations and parameters needed to restore the session later
    • Restack particles to remove filtered out junk particles and then automatically clear deterministic preprocessing jobs that can be re-run later if needed
    • Clear intermediate results of iterative jobs across a project or workspace
    • Clear killed and failed jobs that take up disk space but can’t be further used
  • Featuring a comprehensive Cleanup Data user interface, on-demand refreshing of project and job size statistics, data usage summaries in the project details sidebar, and new right-click menu options for selecting ancestors and descendants of jobs manually. See the Data Cleanup guide for more details.
Data Cleanup Tool
New
Performance Benchmarking Utilities
  • A new system for measuring and comparing key aspects of CryoSPARC performance across CPU, File system, and GPU operations. The benchmarking jobs break down critical elements of CryoSPARC high performance code paths and measure detailed timings to shed light on which parts of a system may be bottlenecking performance.
  • A new performance benchmark user interface allowing for visual comparison of different benchmark runs as well as reference benchmarks published along with CryoSPARC. The interface can display detailed timings from benchmarking jobs or job runtimes from full runs of the Extensive Validation (previously called Extensive Workflow) test set.
Performance Benchmark Interface
New
Particle caching in CryoSPARC jobs now support multiple threads (default 2), increasing copy speed on certain filesystems. To modify, specify CRYOSPARC_CACHE_NUM_THREADS in cryosparc_worker/config.sh. Read the guide for more information.
Multithreaded caching
New
Interactive Job Improvements
  • New plots, displays, and interactive tools across all interactive jobs, including a new exposure image grid view in the Exposure Curation job for ease of assessing and manually curating exposures, and the ability to set threshold parameters when starting the job to bypass interaction and automatically filter data.
  • Several usability enhancements, including:
    • Extraction is now optional in the manual picker
    • Datasets without pick statistics can be used in Inspect Picks
    • Charts in Exposure Curation remember their expand/collapse state when reloaded
    • Exposure Curation now displays particle picks if available
    • Optimized micrograph image loading for faster response times
Exposure curation card grid
New
Extensive Validation (previously called Extensive Workflow) job extended to support multiple datasets and also has a new “Benchmark” mode where timing results are reported and browsable using the new Performance Benchmarking system.
Extensive Validation benchmarking mode
New
The cryosparcm compact command can reduce the amount of disk space used by the MongoDB database. This, along with other steps, may be useful for reducing used storage space in instances with large database sizes. See the Guide: Reduce Database Size for more details.
Update
Interactive job improvements:
  • Flipped Select 2D resolution threshold selection option for clarity
  • Added total picks across all exposures as info badge in Manual Picker top bar

Update
2D Classification, 3D Classification, and 3D Variability Analysis jobs will now produce intermediate results at each iteration, but will delete intermediate results from previous iterations as each new iteration completes. This behaviour can be turned off with a project-level or job-level parameter that will keep all intermediate results.

cryoSPARC v3.0

December 9, 2020

We’re excited to announce another release of cryoSPARC packed with new features, performance optimizations and various stability enhancements:

CryoSPARC Live New

New
New and improved cryoSPARC Live app, redesigned and reworked for robust and seamless real-time end-to-end cryo-EM data processing. CryoSPARC Live is built for data collection facilities, cryo-EM cores, industry labs, microscope operators and individual users who want to perform real-time cryo-EM data quality assessment and decision-making based on streaming 2D and 3D results that update in time with new data. CryoSPARC Live is also now the best and fastest way for users to perform their first-cut processing and curation on already available data.
  • Expedited and optimized preprocessing, enabling up to 600+ movies per hour per GPU (motion correction, CTF estimation, particle picking and extraction)
  • The ability to seamlessly reprocess data at any time, to curate exposures, test/refine picking strategies and the choice of particles for refinement, on the fly
  • Streaming 2D classification, in-line Ab-initio Reconstruction, and Streaming high-resolution 3D Refinement, which update automatically as new particles become available
  • Seamless integration with cryoSPARC, allowing for direct advanced processing from the results generated in cryoSPARC Live without any data shuffling

After extensive beta testing globally, cryoSPARC Live is now available free of charge for general academic use. To learn more and to access Live, please see: guide.cryosparc.com

Update
Renamed internal installation directories from cryosparc2_* to cryosparc_*
Fixed
Import Particles job fixes: Importing particle locations using micrographs created in v2.15+ failed because of a variable length UID prepended to the path of each micrograph; Using the "ignore raw data" parameter causes the job to fail with a missing pixel size error; Support for offsets specified in angstroms (_rlnOriginXAngst, _rlnOriginYAngst).
Fixed
Import result group fails if some path fields are blank.
Fixed
Inspect Picks "use_denoise" button failed to actually load denoised micrographs, even if they were connected.
Fixed

cryoSPARC v2.13

January 28, 2020

v2.13 is packed with a number of updates including interactive 3D variability analysis, reduced memory requirements for refinement of large box sizes, seamless support for negative stain and phase plate data, and more!

New
The 3D Variability Display job output now includes an in-browser, in-line interactive 3D scatter plot to analyze clusters in the distribution of particle reaction coordinates! The user can select which three reaction coordinates to display, and individual clusters can be shown or hidden. Read the new full tutorial, including examples of results:
3D Variability Display 3D Scatter Plot
New
When inspecting particle picks from template or blob pickers, particle pick scores (NCC) and power scores are automatically calibrated with respect to the defocus of each micrograph. This ensures that setting an appropriate threshold on one micrograph will yield good picks on other micrographs with very different defocus.
New
Negative stain and phase-plate datasets are now more easy to process. A single toggle can be set during import and no other parameter changes are necessary in subsequent job types.
New
The blob picker can now use "ring" shaped blobs, which perform well in picking viruses and other spherical particles (eg. apoferritin).
New
Relion 3.1 format .star files can now be imported without errors, though optics group data is not currently parsed.
New
Manual picker interactive job now has adaptive robust contrast normalization to make seeing particles in imperfect images easier.
New
Manual Picker interactive job now includes a "Contrast Intensity Override" slider that allows users to manually select the contrast bounds when viewing a micrograph. The average, patch-based intensity is used by default for the Manual Picker and Exposure Curation jobs.
3D Variability Display 3D Scatter Plot
New
Validation (FSC) Job: Validation of a refinement result (i.e. half-maps) using the FSC is now available as a separate job type, with optional mask input.
Update
Fourier-space plots in Homogeneous Refinement display correctly.
Update
Multiple updates to Topaz-wrapped jobs in cryoSPARC:
  • Added multiprocessing to substantially improve preprocessing times in all Topaz jobs
  • Added parameter to select number of CPUs in the Topaz Extract job
  • Topaz jobs now automatically account for negative stain data
  • Topaz-extracted particles no longer cause 2D classification jobs to occasionally fail due to inconsistent CTF outputs
Update
Passthrough output files now include the project and job numbers for easier referencing (e.g., P1_J1_passthrough.cs)
Update
Manual Picker job now fails by default if the CTF inputs are not connected. An override switch has been added to allow manual picking without CTF estimates, which is not the recommended workflow.
Update
3D Variability Display can now flip the handedness of output volume series.
Fixed
CPU and GPU memory usage of Homogeneous Refinement is substantially reduced. In tests, it is now possible to refine a 1024 box size on a 11GB consumer-grade NVIDIA GPU (GTX 1080Ti), though this does require ~160GB of CPU RAM. A smaller 256 box size can run on a 4GB GPU and requires only 6GB of CPU RAM.
Fixed
The template picker now uses substantially less GPU memory for large micrographs (e.g., K3 super-resolution data).
Fixed
Local per-particle motion correction of K3 data now works correctly.
Fixed
Bug that would cause cufftInvalidPlan error during refinement.
Fixed
Bug where two Select 2D jobs are jobs connected to each other, the last Select 2D job shows incorrect class average thumbnails.
Fixed
Bug where the command_vis would repeatedly try to start but fails, using 100% CPU in the process.
Fixed
(Added in v2.13.2) Bug where mrc volumes were being saved as float64 files, which the mrc file format doesn't support, causing the Sharpening Tools job to fail
Fixed
(Added in v2.13.2) Bug where Heterogenous Refinement and Multi-Class Ab-Initio jobs would fail due to a ValueError

cryoSPARC v2.12

November 29, 2019

Major updates to 3D Variability: Solve more modes, smaller motions, automatic classification of discrete classes, and more!

New
New "cluster" mode in 3D Variability Display allows for automatic hierarchical 3D classification based on variability coordinates: directly visualize and see how many discrete classes are present in a dataset, separate them by clustering, and reconstruct each separately. Then recursively perform 3D Variability to look for sub-conformations or flexibility within each cluster, or refine each cluster separately.
3D Variability Analysis
New
New "intermediates" mode in 3D Variability Display allows for weighted reconstructions of intermediate positions along each variability dimension: create more detailed videos of variability that minimize the effect of density appearing and disappearing during large motions. Also output weighted particle subsets for intermediate positions, for refinement of particular flexible conformations.
New
Default options in 3D Variability improve sensitivity to small variations in the 3D density. Plus support for coloured or white noise models, high-pass filter during optimization, per-particle scale optimization.
Fixed
Fixed streaking issue so that (many) more variability modes can be solved simultaneously.

Major updates to 3D Refinement: On-the-fly CTF refinement, aberration correction, exposure groups, substantial speed improvements!

New
Per-particle defocus refinement implemented on GPU allows CTF refinement in minutes for 100,000's of particles. Implemented as a standalone job and also as an in-line on-the-fly option during Homogeneous Refinement.
High-Resolution Structure
New
Global CTF Refinement and Local CTF Refinement jobs: CTF aberration support, also GPU implemented, corrects for beam tilt, trefoil, spherical aberration, and tetrafoil. Estimation of the new parameters can be done in a standalone job or as an in-line on-the-fly option during Homogeneous Refinement, yielding ultra-high resolution reconstructions.
Local CTF Refinement job card
Global CTF Refinement job card
New
New Exposure Group Utilities job allows users to split or combine datasets into multiple exposure groups for higher-order aberration correction. Create exposure groups using regular expressions and separators, and test your exposure group creation strategy.
New
First-pass optimization of GPU and CPU code for Homogeneous Refinement: now up to 5x faster, especially for symmetric particles.

New UI-based User Management System

New
New admin page with ability to change roles of existing users and create new users through the UI
List of users and new user form

Topaz Integration Beta

New
New Topaz wrapper jobs for integrating Topaz's particle picking and micrograph denoising functionality
  • Topaz Train, Topaz Cross Validation, and Topaz Extract jobs perform particle picking while the Topaz Denoise job performs micrograph denoising
  • Users only need to install Topaz to incorporate it within the cryoSPARC pipeline
  • Denoised micrographs are compatible with Manual Picker, Inspect Particle Picks, and Topaz's particle picking pipeline, assisting users and machine learning models in observing micrographs
  • Tutorial Topaz integration in cryoSPARC
