Notes It may be useful to use this application in a small script that extracts all sequences from a multiple sequence file and explicitly names the output files in the way that you require. Diagnostic Error Messages None. It always exits with a status of 0. Known bugs None. The program seqretsplit will take a file containing many sequences and will output many files, each containing one sequence.
