im doing a presentation on DNA sequencing and its uses and i was hoping
to give a description of database searches. ive used BLAST before in my
research, but unfortunately i never really understood what was going on.
id appreciate it if someone out there could provide me with a short
summary (their own or a reference which contains one or an FTP site) of the
BLAST algorithm and the numbers that are returned with a search (score, expect,
etc.) in language that your typical first year mol bio grad student with
little background in statistics could understand. ive looked back
through some of the references, but i found them just as confusing. id
really appreciate any response.
ps. the presentation is on tuesday...
