WebA Position Specific Scoring Matrix, or PSSM, is a matrix of :index:`log-odds ratios` per position of a sequence motif. (PSSMs are also called :index:`profiles`.) They provide a means for computing the match odds for any new sequence. They are typically applied to finding transcription factor binding sites (TFBS) but are also used to ... WebThe algorithm is called PPIevo and extracts the evolutionary feature from Position-Specific Scoring Matrix (PSSM) of protein with known sequence. The algorithm does not depend on the protein annotations, and the features are based on the evolutionary history of the proteins. This enables the algorithm to have more power for predicting protein ...
