open-cravat is an open-source platform for rapidly developing, using, and disseminating variant annotation tools.

It can handle unlimited number of variants in VCF format input files as well as its own input format and produce tab-separated text output files and excel spreadsheets. It is command-line-based as well as GUI-based. Its web visualization tool gives interactive filtering and sorting and tables and "widgets" which are graphic components to show annotation results (network graphs and gene diagrams with your variants on, for example). It is written in Python and installed with a pip install and has its own module manager.

It is modular and open-source, and it is easy to write input and output format converters and custom report generators as well as custom annotators and gene mappers. You write only minimum parts specific to your module since heavy lifting is done by open-cravat. You can publish your converters, report generators, annotation modules, gene mappers, and etc with one command to cravat store for other people to install and use also with one command or one click. There are 44 annotation modules as of today and more are being added.

Its GUI components are being rapidly polished but its command-line interface is quite stable. Let me know if you have any question or suggestion about open-cravat.

Hello slcrick!

I would like to know if it is possible to extract variants from selected variant annotators with custom information, for example, frequency and gene name. I know that I can download manually all databases, but it is simpler if I can use your tool because it is up-to-date and I don't want to download two times the same database (such as 1000 genomes)

  • Python requirement has been increased to Python 3.6 or higher.
  • Log file has non-redundant exception messages for better readability.
  • Record of annotation modules are correctly kept with multiple cravat runs on the same input.
  • For a job with multiple input files, output file names start with the first input file name plus _and_x_files, where x is the number of input files minus 1.

cravat GUI

  • Job list is automatically updated when there are running jobs.
  • Running jobs can be cancelled from the GUI.
  • Warns if a job has more input lines than specified in Settings.
  • GUI remembers genome assembly selection.
  • Variout user interface improvements
  • Fixed various bugs.

Web Store

  • Module installation can be cancelled from the GUI.
  • Shows module group, a collection of the varieties of a module.
  • Warns with total size of installation for collective installation or update.
  • Module tile shows their module types if they are not annotation modules.

Result Viewer

  • hg19 and tagsampler results show next to Variant Annotation columns.
  • Less-informative widgets are hidden by default.

Modules

  • Protein Diagram widget on gene tab shows all variants for a gene on a table, whose rows when hovered will highlight corresponding variants on the protein diagram.
  • 1000 Genomes module group and CHASMplus module group have been published.
  • Comma-delimited format reporter and tab-delimited format reporter have been published.

1.4.3

April 30, 2019

GUI

  • Improved the launch speed.
  • Detects the absence of the server and prevents further operation.
  • Multiple open-cravat GUI browser tabs work properly with install/update.

Web Store

  • Prevents installation/update of modules if free disk space is not enough.

1.4.2

cravat core

  • cravat can process multiple vcf-format input files at once.
  • cravat better handles status and error logging. *Annotation modules run in multiple execution of cravat with the same input are accummulatively logged in the job status file for the input.

cravat GUI

  • open-cravat command-line terminal can be launched from the GUI.

Web Store

  • Improved launch speed.
  • Fixed alphabetical name sorting of modules.

Result Viewer

  • Simplified and improved the default settings of the basic load-filter.
  • Added context menu to the column groups for each module on the result tables.
  • Improved the layout and user experience of the table columns and widgets.
  • Improved launching speed.
  • hg19 coordinates, samples, and tags appear right next to Variant Annotation columns.
  • Summary widgets without any result will hide themselves.
  • Fixed wrong drag-and-drop of column headers

Modules

  • Improved the speed of REVEL module.
  • Smarter detection of vcf input format (vcf-converter)

1.4.1

March 21, 2019

Result Viewer

  • Revamped the Summary tab.
  • Fixed the load filter for the cases where samples were searched with "not".
  • Added context-menu to the result table columns.
  • Result table cell value area can be expanded to display large text strings.
  • Columns of the result table can no longer be nested in another column group.

CRAVAT web GUI

  • Added functionality to navigate between different module dialogs in store using arrow keys.
  • Decluttered the interface of the web store by completely hiding base components.
  • Added separate input examples for hg18, hg19, and hg38.
  • Module detail panel in web store describes the output columns of the shown module.
  • Updated look and feel of the web submit and the web store.

cravat

  • Dependencies (between modules and between open-cravat and modules) are resolved before module installation and update.
  • Decluttering of the log file for better readability.
  • Each run creates an .err file which explicitly reports each variant with an error.
  • Added the capability of cravat-admin to privately publish modules.
