If you can search with FASTA with multiple fasta query sequences, you are not
using the standard FASTA package on a Mac or PC. None of the programs that
I distribute on those platforms work for multiple queries.
Under unix, you can search with several queries in a file using the
MPI or PVM parallel versions. Unfortunately, the unix versions of the
standard fasta programs do not work with multiple queries.
