How do you customise database for blast?
Step 1. Assemble your sequences.
Put all your sequences in Fasta format in a single file.
This file should be located in a suitably named
subdirectory of your home directory on the UBiC Blast
server. The definition line for each sequence should start
with a unique identifier for that sequence.
Step 2. Convert this sequence file to a Blastable database.
The command formatdb converts your Fasta file of sequences
to a set of files that can be queried with command-line
BLAST.
Step 3. Test Blast on your database.
See the UBiC tutorial, Using Command-line BLAST. In the
blastall command-line you will need to specify the location
of your database by typing: -
d /disk2/home/myhome/blastdbs/custom.aa.

How to compare a DNA sequence to itself by using it for both the 1st and 2nd sequence?
Suppose the Blast search returned 100 hits. Of these, 17 were false positives and we knew that there were 165 sequences in the database which should have returned a hit with our sequence. How many false negatives were there, and what is the sensitivity and selectivity of Blast in this instance?
