We purchased the BandScanner software at the beginning of this year and
have had mixed fortunes. In its favour, this Software is one of the less
expensive alternatives currently available and used in combination with
Assemblylign it is an improvement on manual entry of gels. In particular
the ability to locate and view conflicting base positions quite quickly is
obviously a big advantage. HOWEVER, the technical support from IBI is just
about non-existent, and Anthony Otsuka is right to say that the sequences
sometimes need a lot of editing. I have found the same problem that he
reports - too many background bands - but I think with experience it's
possible to overcome this problem without too much difficulty. I should
add though that we are accumulating data from large numbers of homologous
sequences and insertions/deletions are very conspicuous when we come add
sequences to our existing alignments. Therefore I am confident that after
a relatively small amount of editing it's possible to get very accurate
sequences. If you were to use this software for sequencing long clones of
undetermined homology you would have to sequence both strands completely
and have lots of long overlaps in order to get accurate sequences.
