So those of you who use the Tools::RemoteBlast module, please read
the following email. We need some people to test out how much the
parser breaks with the "new" formatter. Tests seem to pass right now,
but I don't know if that is because the 'old' format is being
requested still. Could someone please take a little time to see
what's going on and report back.

> New features:
> 1.) The new formatter will present the masked residues or bases as
> lower-case letters. Additionally the masked letters can be shown
> in color.
> To use this feature change the "Masking Character" to "Lower case"
> on the
> formatting page and select a "Masking Color".
> 2.) The "pairwise with identities" option allows easy
> identification of a
> few mismatches among highly similar sequences. In this (pair-wise)
> mismatches, as well as "Sbjct" (on the line containing the
> mismatch) are
> shown in red.
> To use this feature change the "Alignment view" to "Pairwise with
> identities" on the formatting page.
> 3.) For database sequences longer than 200,000 bases each alignment
> has a
> header entitled "Features in this part of the subject sequence"
> listing CDS features on the database sequence within the alignment
> range or
> at the 5' or 3' end if not features are within the range itself.
> This gives a quick description of what you are looking at as many long
> sequences have a standard defline such as "chromosome 16".
> Rewrites/bug fixes:
> 1.) The graphic overview has been rewritten; it now uses an HTML
> 2.) Query-anchored views now work with blastx/tblastn/tblastx, they
> 3.) phi-BLAST patterns are now also shown in the query-anchored view.
