BLAST software?

[Rudi Effe]

Hi there,

I am doing research on mutations of a Bacteria. Using BLAST on the web,
I get alignments like

Query:  21 TGCTGT...
           || | |...
Orig.: 321 TGGT-T...

where 98% are identical (600+ positions).

I need a survey, which sample query mutates at what positions. So far I
seem to must check manually: Write down the positions for each query and
so on. Is there no way to do a multiple compare? Or even create the
table of differences automatically?

Thank you for any hint!
