    • Convergence detection in mProphet modeling and 10 iteration maximum (down from 30)

Skyline v0.5 Preview Updated on 8/14/2009
Skyline v0.5 Preview Updated on 7/7/2009

Skyline v0.5 Preview Released on 5/30/2009

The core focus of v0.5 is analysis of result data, building on the successful method creation features of v0.2. Our ASMS 2009 poster gives a broad overview of how we are using these features to extend the scope of our targeted proteomics research at the MacCoss Lab.

New features include:

  • Scheduled and unscheduled transition list support for instruments from:
    • Agilent
    • Applied Biosystems
    • Thermo Fisher
    • Waters
  • Import of results data for instruments from:
    • Agilent (native)
    • Applied Biosystems (native)
    • Thermo Fisher (native)
    • Waters (native with MassLynx 4.1 installed)
    • All of the above converted to mzML or mzXML
  • Share methods and results across labs with different instruments, using Skyline's high-performance, compact data caching
  • Build your own spectral libraries from Mascot and X! Tandem search results
  • Multiple sample replicates, and multiple replicate import
  • Chromatogram plotting with dynamic layout for multi-replicate viewing
  • Peak detection and advanced peak picking
  • Peak quality indicators
  • Isotope labeling ratios
  • Advanced peak integration editing
  • Dynamic report designer
  • Retention time analysis views:
    • Linear regression
    • Replicate comparison
    • Scheduling

 

Skyline v0.2 Released on 2/17/2009

Skyline is a Windows client application for building Selected Reaction Monitoring (SRM) methods. It aims to employ cutting-edge technologies for creating and iteratively refining SRM methods for large-scale proteomics studies. The latest version of Skyline contains support for:

  • Full featured SRM method editing
  • Transition list export for Thermo Finnigan TSQ and ABI Q-Trap
  • Retention time prediction
  • Isotope labeling
  • Spectral libraries (NIST, GPM, BiblioSpec)
  • Building spectral libraries from your results in TPP pepXML/mzXML

Skyline edits its own universal method format document (saved in XML), and can export transition lists for a variety of instruments. For large, un-refined methods these may be multiple lists per document.
