Seqal doesn’t run on 32-bit platforms
We have tested Seqal on 32-bit platforms and have found it not to run. We haven’t made this issue a priority since we expect most users to be running on a 64-bit platform.
Seal doesn’t handle single reads
At the moment PairReadsQSeq and Seqal only work with paired reads. If you want to align single reads, you can “hackishly” assemble a prq file that contains the same read as 1 and 2 and feed it to Seqal.
The alignment algorithm is implemented in libbwa, which is a modified and refactored version of the BWA short read aligner.
The Seal logo was pieced together from a seal image by mushko released in the Open Clip Art Library, and the Hadoop elephant.
