Implementation of Dynamic Statistical Comparisons

The project wiki is the main source of documentation for both developers and users of the DSC project. If you are new to the concept of DSC, it may worth reading this blog post to understand the motivation behind this project.

This work is supported by the the Gordon and Betty Moore Foundation via an Investigator Award to Matthew Stephens, Grant GBMF4559, as part of the Data-Driven Discovery program.

Developer notes

Upgrading DSC to latest development version

For most users, we recommend installing the most recent stable release. If you would like to upgrade your existing installation of DSC to the most recent (unstable) development version, follow these steps.

DSC is closely developed in parallel with SoS. Therefore, the development version of DSC (maintained in the master branch of the GitHub repository) typically requires the development version of SoS.

Install the latest SoS

git clone https://github.com/vatlab/SoS.git
cd SoS
pip install -U --upgrade-strategy only-if-needed .

Install DSC from source

git clone https://github.com/stephenslab/dsc.git
cd dsc
./setup.sos

Or, if you have downloaded it before,

cd dsc
git pull
./setup.sos

Change Log

Upcoming release

Goal for 0.2.8

• Support for multiple outputs per module, for shell executables

• Improve command options for scripts

0.2.x

0.2.7.5

• Add package installation and version display with -h option.

• Add .gitignore to cache folder when a git environment is detected.

• SoS bumped to 0.9.13.3 that now bundles the pbs module.

0.2.7.4

• Improved R’s sessionInfo format.

• Bug fixes #119, #121, #122

• [minor] Error message improvements.

0.2.7.3

• More stringent R library and command executable check.

• [minor] Fix a regression bug on path due to 0.2.7.2.

0.2.7.2

• Improved Windows path support.

• [minor] Fix a bug with nested tuple with raw().

0.2.7.1

• Dump individual data object with scripts using dsc-query *.pkl and dsc-query *.rds.

• [minor] Improve behavior for length 1 vector in R’s list with R() operator.

• [minor] Various bug fixes.

0.2.7

• #92 paired parameter input convention.

• #90 and #93 use Rmd files as module executables.

• #94 and #95 added DSC::replicate and command option --replicate.

• Enhance R() operator due to use of dscrutils package. This packages is now required to parse DSC file when R modules are involved.

• Add, by default, a variable DSC_DEBUG to output files that saves various runtime info.

• SoS bumped to 0.9.13.2

  • Support R github package force install when version mismatches.

  • Fix bug with --touch option.

  • #97 Improved error logging and reporting behavior.

• [minor] Revert from ruamel.yaml to yaml for better performance.

• [minor] #96

• [minor] #98

• [minor] Various bug fixes.

0.2.6.5

• Bring back partial mixed languages support. Piplines with mixed R and Python code can communicate data of limited types (recursively support array, matrix, dataframe), via ``rpy2`` as in versions prior to 0.2.5.x. Support for additional languages will be implemented on need basis with HDF5 format #86.

0.2.6.4

• Add a dsc-io command to convert between python pickle and R RDS files – an internal command for data conversion and a test for rpy2 configuration.

0.2.6.3

• Inline module executable via language interpreters (eg. R(), Python()).

0.2.6.2

• [minor] Ignore leading . in file(): file(.txt) and file(txt) are equivalent.

• [minor] Disallow derivation of modules from ensemble.

• [minor] Various bug fixes.

0.2.6.1

• Internally replace RDS format with HDF5 format for Python routines. Pipeline with mixed languages is now officially broken at this point until the next major release that supports ``HDF5`` in R.

• SoS required version bumped to 0.9.12.7 for relevant upstream bug fixes for remote host computing.

• [minor] Various bug fixes.

0.2.6

• Bring back --host option; add a companion option --to-host to facilicate sending resources to remote computer.

• Add --truncate switch.

• SoS required version bumped to 0.9.12.3 for relevant upstream bug fixes.

• [minor] Improved command interface.

0.2.5.2

• SoS required version bumped to 0.9.12.2 for relevant upstream bug fixes.

0.2.5.1

• Change in seed behavior: since this release seed will no longer be a DSC keyword. Users are responsible to set seeds on their own.

• New syntax release, compatible with SoS 0.9.12.1.

• Removed --host option due to upstream changes.

0.1.x
