Skyline v3.7 Released on 6/12/2017
New features include:
- Extensive performance improvements in speed and memory use for proteomewide, label-free DIA and DDA data processing
- If you have the hardware, Skyline should be able to use up to 100% CPU and 100% of your memory. Though we continue working on making it do more with less.
- Performance improvements in very large DIA (6,000,000 transitions x 20 files)
- Convergence detection in mProphet modeling and 10 iteration maximum (down from 30)
- New --import-process-count=[num] and --import-theads=[num] arguments for SkylineRunner. The former can yield up to 10x import performance improvement on a 24-core NUMA server and 2-4x on a standard i7.

- Multi-peptide peak area graph
- Customizable color schemes
- Import isolation scheme feature from DIA data files
- Improved iRT calibration from DDA data directly into spectral libraries
- Storing raw chromatograms in SKYD files. This is a big one which also gives us:

- View > Transform > None (Shift+F12) shows the raw uninterpolated chromatogram
- Skyline can now always show in Full-Scan graph every spectrum from which chromatograms were extracted. Previously interpolation could cause spectra to be skipped

- Fix to View > Mass Errors > Replicates graph to match colors with other replicate graphs when MS1 and MS/MS XICs are present
- Fix y axis scaling in chromatograms which had problems when IDs or Predicted annotations were present and scale was less than 100
- Fix tracking of changes to iRT standards to better match changes to documents
- Fix to avoid removing iRT standards when Edit > Refine > Advanced minimum transition count is higher than they contain
