We don't have a standard program for reading fasta format files. If your
sequence input is a single fasta file containing multiple sequences then you
could use a simple script to split them up. The following should work:
-----------------------------------------------------------------------------
#!/usr/bin/nawk -f
BEGIN {
file="";
}
/^;/ {
next;
}
/^>/ {
gsub(">", "");
if (file != "") {
close(file);
}
file=$1;
print "Creating", $1;
next;
}
{
print $0 >> file;
}
END {
close(file);
}
-----------------------------------------------------------------------------
This is a 'new awk' script. You may need to adjust that first like to awk,
gawk, mawk (or whatever is available on your system). The script is rather
simplistic, so the best strategy is to make a new directory first.
Eg:
mkdir split
cd split
fasta-split < ../fasta_seqs
I hope this helps.
