Hello,

I am looking for a RandomAccessFile-like class that can read small, arbitrary chunks of a very large (like 250K of human DNA) fasta file. (UCSC chromosomal fasta files contain just 1 sequence for the whole chromosome). I was hoping that someone may have already written a class that will take in an alphabet and a range (maybe in the form of a RangeLocation object) and will return the sequence in that range from the file. I would hate to spend time re-inventing a wheel that may already exist.

Thanks,
Todd
