[BiO BB] custom blast server

Here is the deal. I am assuming that you suggest that I dump all my
sequences, format them, and use the BLAST executable provided by NCBI,
right? I thought about that too. However, The application is going to make a
BLAST request over the internet and the BLAST server needs to thread (so we
can handle many concurrent connections) and return the BLAST results to the
application when the search is complete. I could make a wrapper type server
in Perl, but I think that is a bad idea. I would like to have something
cleaner. Ideally I would like to have a Threading server that handles BLAST
requests via XML RPC or something like that and integrates better with my
application. Am I making any sense here?

I do not know the answer to your specific question. However, I am a bit
curious as to why you would like to run BLAST vs. an SQL database. You can
easily convert any data you may have to a flat format fasta file, and then
use NCBI tools formatdb to create the format which BLAST recognizes. A
table which translates from your FFFF to the SQL key fields can correlate
between the two, in case you have more than just sequence information in
your SQL database.
This is not a criticism of your choice of methods, I was just wondering
what is the application demand that makes you want to take the trouble. I
have toyed with the idea of doing something similar myself, but I always
caved in and resorted to the method above.
But hey, if you write up such a thing, that would be really cool!
