[Chimera-users] match-align using just selected protein areas ?

[Elaine Meng]

Hi Marek,
Yes, if you mean MatchMaker (Match->Align does not align the structures, it just makes a sequence alignment from a structural alignment you already made).

In the MatchMaker GUI, there is a "Further restrict matching to current selection" setting:
<http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/matchmaker/matchmaker.html>

In the matchmaker (mmaker) command,
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/mmaker.html>
... it is similar but you instead specify the residues directly instead of selecting them:
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/mmaker.html#restrict>

I hope this helps,
Elaine
