          Description

          Users tried to use a fasta.gz file as the sequence for a custom genome.
          This didn't work. IGB will work with fasta, but not fasta.gz.

          This was brought to our attention through this biostars post:

              Testing...

              using A_thaliana_Jun_2009.fa
              $ gzip A_thaliana_Jun_2009.fa
              > A_thaliana_Jun_2009.fa.gz

              IGB was able to read the fa.gz file just like the fa. If I drag/drop it into IGB, it lads a single long sequence feature representing each chromosome. If I select it as a custom genome it loads the genome sequence.

              Note that gzip is not the same bgzip.

              This addresses a user-reported bug.

              I will likely include this in the release.

              Please make a note to notify the person who reported this when the new version comes out so that they can update their IGB.
