CHARMM Development Project Forums User Discussion & Questions Setup, I/O, and Basic questions get RESId from selection?

Hi CHARMM users,

is it possible to get the RESId from a (defined) selection?

For example:
If I want to know which residues are affected by this selection:

define SET sele prop X .lt. 10 end

How can I get this information without looping over all residues and check each resid on its own?

Cheers,

There are some ?SEL* substitutions (select,doc, subst.doc), but they only report info for the first residue in the selection. However, you can loop over selected atoms via the .SUBSET. operator (select.doc), which may be useful.

Aiii, I totally forgot .SUBSET.!
This will do, since I don't really need to know each RESID in the selection personally and by ID ;-)

Thanks a lot!

Cheers,
Bjoern
