For example, a specific 50-mer will occur once in 4^50 ( or 1.267 E 30).

... Hi everyone,
I have a large fasta file and need to bin it by size: everything 200 nt and up in one file, and everything 199 or smaller in another. I have found some useful scripts that will remove the smaller sequences, but they are discarded and I need to keep them in a separate file.

... Hi everyone,
I have a very large file of genomic sequence, and need to bin them by the presence or absence of a specific 20-mer. (Everything with the 20-mer in one file, everything without it in another). I tried using grep but the sequences are multi-line.
Any suggestions will be appreciated.
