[Biojava-l] Looking for a RandomAccessFile-like class for sequences

[Todd Riley]

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
