METHODS AND SYSTEMS FOR PROTEIN AND PEPTIDE EVIDENCE ASSEMBLY

摘要

The present teachings provide methods and systems for the identification of proteins via peptide analysis. Some embodiments analyze proteins identified by analysis techniques such as mass spectrometry and build protein groups out of results. Groups can be formed by collecting like proteins and examining the group so as to identify if it is likely that only one form of a protein is present or, if there is enough evidence to support the presence of alternate forms. Various embodiments provide visual reports that can be interactive. These reports can allow a user to visualize relationships between proteins both intra- and inter-group. Methods are also introduced that can reduce the identification of false positives by taking into account a priori information.
