Scaffold Q+ for Proteomics

Search Software

Scaffold is a computer program that integrates search results from search algorithms such as Sequest, X!tandem ,Mascot, Phenyx, OMSSA and Spectrum Mill to generate peptide identification and protein identification probabilities. Scaffold also displays an overview of the protein identifications for each search algorithm so that spectral identifications can be compared and validated by probability scores. Protein information can also be used to detect false positives and also examine the peptide and spectral evidence used for identification.

Scaffold Q+ helps in quantitation of 4-plex and 8-plex (iTRAQ) and 6-plex (TMT) biological samples.

           New features in Scaffold 4.0.6.1

  • New Local FDR-based scoring system replaces the PeptideProphet for validating peptide identifications.
  • Modified weights for protein probability calculations are used in the ProteinProphet algorithm to more accurately model peptide assignments.
  • Protein clustering has been added to catalog protein groups sharing similar sequences.
  • New FDR filtering has been added to the standard probability filters.
  • Multi selection of proteins has been added to enable you to perform certain operations simultaneously.
  • Quantification and differential GO term filtering enable new biological questions to be considered.
  • Scaffold now supports any search engine that implements the mzIdentML HUPO standard.
  • Scaffold's mzIdentML export is now compatible with The PRIDE XML converter and Skyline, enabling the creation of spectral libraries for follow up SRM experiments.
  • The new version has also added new terms to capture different types of evidence used in protein clusters.
