For a new cloning project, we needed to access the plasmid maps of an old construct of mine (pSecTagN2, which was a precursor of pMosaic, aka pSecTagI) which I had composed from many different sources in 1999.
1. Save all sequences in one flatfile format (NOT MacVector format), e.g. genbank format.
2. Copy all sequences to a Linux/UNIX computer and convert them from Mac format to UNIX format: mac2unix *.gb
3. Write all sequence fiule names into one file: ls *.gb > oligo.lst
4. Convert all sequences into one file of concatenated fasta entries using EMBOSS: seqret -sequence @oligo.lst -osformat fasta. Call the output file "mcbl_oligo_db"
5. Put this fasta file into the blast web servers database directory (.../blast/db)
