eMATRIX 2.0
:: DESCRIPTION
eMATRIX performs the following functions:
(1) EMATRIX-SEARCH: EMATRIX-SEARCH determines the function of a sequence. Given a protein sequence, EMATRIX-SEARCH identifies the sequence by finding matches with a precompiled database of scoring matrices. The scoring matrices are generated by the EMATRIX-MAKER program for each alignment block in a given database, such as BLOCKSPLUS. EMATRIX-SEARCH has been optimized for speed, and can be used for genome-wide functional analysis.
(2) EMATRIX-MAKER: EMATRIX-MAKER converts an alignment block into a minimal-risk scoring matrix, for use in sequence analysis. EMATRIX-MAKER is used primarily in batch mode to construct the databases for the EMATRIX-SEARCH program. However, the EMATRIX-MAKER program can also be used to convert an individual alignment block into a scoring matrix. That scoring matrix can then be used by EMATRIX-SCAN program to scan a sequence database for homologs.
(3) EMATRIX-SCAN: EMATRIX-SCAN searches a sequence database for sequences that match a given scoring matrix. Such a scoring matrix might be generated by EMATRIX-MAKER.
