**NAME**

LAmerge - merge .las files into a single sorted file

**SYNOPSIS**

LAmerge[-v]merge:lasparts:las...

**DESCRIPTION**

Merge the .las filespartsinto a singled sorted filemerge, where it is assumed that the inputpartsfiles are sorted. Due to operating system limits, the number ofpartsfiles must be <= 252. With the-voption set, the program reports the number of records read and written. Used correctly,LAmergeandLAsort(1) together allow one to perform an "external" sort that produces a collection of sorted files containing in aggregate all the local alignments found by thedaligner(1), such that their concatenation is sorted in order of (a,b,o,ab). In particular, this means that all the alignments for a given a-read will be found consecutively in one of the files. So computations that need to look at all the alignments for a given read can operate in simple sequential scans of these sorted files.
