Bio.Compass

Package Compass

Code to deal with COMPASS output, a program for profile/profile comparison. Compass is described in: Sadreyev R, Grishin N. COMPASS: a tool for comparison of multiple protein alignments with assessment of statistical significance. J Mol Biol. 2003 Feb 7;326(1):317-36. Tested with COMPASS 1.24. Functions: read Reads a COMPASS file containing one COMPASS record parse Iterates over records in a COMPASS file. Classes: Record One result of a COMPASS file DEPRECATED CLASSES: _Scanner Scan compass results _Consumer Consume scanner events RecordParser Parse one compass record Iterator Iterate through a number of compass records
