Overview
--------
fastq-join joins two paired-end reads on the overlapping ends.

Split read ids character: Verifies that the 2 files probe id's match up to char C. Use ' ' for Illumina reads.

Maximum difference is the maximum allowed percentage of bases that differ in the matching region.

Minimum overlap is the minimum number of bases that must overlap (with no more than the maximum difference) for reads to be joined.

Verbose stitch length report is a report for each joined paired of reads showing how large the overlapping section was.

This tool uses sqr(distance)/len for anchored alignment quality algorithm. It's a good measure of anchored alignment quality, akin to squared-deviation for means.  This tool uses the fastq-join program that is part of the ea-utils suite. See http://code.google.com/p/ea-utils/wiki/FastqJoin for details.
