Fix gffread Issue with Processing Large Genomes (Chromosomes > 2GB)

[cjw-gmail]

I modified gffread to address an issue it had when processing very large genomes, especially when a single chromosome exceeds 2GB in length. This issue caused gffread to fail in correctly extracting transcript sequences. I optimized the code to better handle large file reads.

./gffread-master/gffread ref.gtf -g ref.fa -w transcript.fa
