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.
  • Reduced .sky file size by 70% for large (over 1000 transitions) files
  • 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 > Interpolated (F12) shows the chromatograms as Skyline used to show them
    • 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
    • A new report value TransitionResults.PointsAcrossPeak
    • File > Share can now create document archives in 3.6 format for sharing to Skyline 3.6
  • File > Export > Spectral library for exporting targeted results as a spectral library for your next experiment
  • Support for semi-cleavage enzymes in Peptide Settings - Digestion tab
  • Support for Associate Proteins checkbox in View > Spectral Libraries with background proteome for nonspecific cleavage
  • Run-to-run retention time correlation graph
  • New file details (score type, score cut-off, unique peptides and spectra) in Spectral Library Explorer source file details form.
  • Support BLIB files with StartTime and EndTime in the RetentionTimes table
    • Allowing external tools to provide their own peak detection and picking
    • Times are used for peak integration boundaries without further peak detection
    • Faster imports and smaller resulting files
  • File > Import > Peak Boundaries 2-10x faster
  • Add Total Ion Current Area under Results.File in reports/Document Grid
  • Add "Equalize Medians" as normalization method in Peptide Settings / Quantification for large exploratory experiments where most targets are not changing
  • Improved paste performance in the Document Grid
  • Column tips and reference help in the Live Report view editor
  • New SkylineDailyCmd.exe in same folder as Skyline-daily.exe with same command-line interface as SkylineRunner.exe, but runs Skyline in a single process, useful for ZIP-file or Administrator installations where these EXEs are placed in easily located paths
  • Proteome Discoverer 2.2 support in spectral library builder
  • Improved support for SCIEX Midas workflow
  • Improved support for Agilent IMS workflow
  • Improved handling of importing modified peptide sequences with SCIEX 3-letter modification abbreviations
  • Export transition list feature for mixed polarity small molecule documents to allow exporting different polarities separately
  • Various other fixes such as:
    • Use of .NET API to encrypt passwords for Panorama and Chorus stored by Skyline in its user.config file.
    • Fix to z ion mass calculation, which was off by one hydrogen atom
    • 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
    • Fix to keep from duplicating spectrum source files - especially problematic for iRT training - in spectral libraries when a DDA file is searched twice
    • Slightly more tolerant peak grouping which allows undetected peaks to be added to the group based on chromatogram correlation over the integration boundaries.
    • Fix precursor matching with SRM data in fringe case where the precursor m/z is worse, but transition matching is better
    • Fix error message reporting missing required columns in File > Import > Peak Boundaries
    • Fix to "Unable to sort because the IComparer.Compare() method returns inconsistent results"
