Just wondering if you have considered the tools from NCBI. If you were to
dload the blast bundle, I think blast-2.2.17 is the most current release,
you can use formatdb to create a blastable database of your fasta seqs that
you can use for blasting using one of the blast programs or retrieving using
I'm not sure what emboss application you are attempting to use but you could
probably use a for loop to automate some procedure
For i in `cat seqIDs.txt`; do fastacmd -d blastdb -s $i > seq.fsa | primer3
-input seq.fsa -output $i_out.primers
Depending on what you want to do something like that might work for you...
