I see. That's actually really useful to know.

Is this the file that defines the 'entry points' for each sequence
object? i.e. instead of generating this on the fly while processing
the blast results, do it once initially for every sequence object you

Thanks all for the help. Very much appreciated!
P.S. dumb question but... what defines a HIT in blasttable format? is
it strictly the set of HSPs with the same query and subject, or is
phase and relative position also taken into account?
