in reply to Similarity of strings

How did you produce your alignment? Did you use BLAST? http://www.ncbi.nlm.nih.gov/blast" Sequence alignment tools calculate the %identity, %similiarity, %gaps of the alignments they produce. One can then use a parser http://sapiens.wustl.edu/~ikorf/BPlite.html to get at the information you want.

    Yep, I used BLAST, followed my mview (http://mathbio.nimr.mrc.ac.uk/~nbrown/mview/) to prepare an alignment from the BLAST-report.
    But MVIEW doesn't provide the similarity stuff (but does provide e-value, score, and some other things) and I don't have the guts to parse the complete BLAST-report (which can be very big sometimes) just to get the similarity.
    I prefer to check only those sequences which are of interest to me directly.

    Cheerz, Micha

      Perhaps bioperl has a BLAST parser you could use? (I've never used their parsers, so I cannot comment further.)
        I'm using BioPerl already, but I think parsing a 40-200 Mb BLAST-report is over the top and won't save much time (if at all) over calculating the similarities by myself. In fact, that would be a real memory-filler. ;-)
