对于喜欢收藏的主题搜索MHC肽

This utility helps in the search for MHC-like motifs in collections of peptide sequences obtained from proteomic analyses. Motifs will search for sequence motifs characterized by an anchor position defined by the presence of one or several specific amino acids and will determine the frecuency of the different amino acids in each position in the sequence to the right (C-terminal) of the anchor. Amino acids defining the anchor and the motif size are selectable. An additional position in the peptide (relative to the anchor) can be defined as a second anchor in order to search for more restricted sequence patterns. Results are displayed graphically and stored in an MS Excel file in the form of frecuency tables (absolute and normalized values). Graphics are also embedded in the Excel document for convenience.
