With a lot of reads, snap-aligner is not able to sort the bam file without a very large amount of memory. To reduce the required memory, this patch will run snap-aligner with each fastq or pair of fastq from the list and delegate merging and sorting to samtools. Please be sure to have the samtools command in your PATH because the availability of this new dependency is not checked by the TransRate patched version.</p>
