Module	Description
TMAP map1 options	BWA-short reads mapping. Very fast at finding perfect matches. Very slow at finding a set of matches with up to two mismatches.
TMAP map2 options	BWA-long / BWASW reads mapping.
TMAP map3 options	Simplified SSAHA, based on a k-mer lookup table.
TMAP map4 options	Based on the BWA fastmap routine. Searches for the maximum exact matches between the reads and reference.
TMAP mapvsw options	A vectorized implementation of Smith-Waterman. A single mapping strategy that is twice as fast as the other modules. Modified to improve specificity.
