Any calculation function in CCP4 to analyze coordinate file?

Dear members,

Just have a silly question past my mind: is there any program in CCP4 can be used to analyze coordinate file (.pdb format) to have a very general/overall discription about the structure? --such as the total number of protein residues/water/ligand, the total atoms of protein/water/ligand, the average b-factor of protein/water/ligand, the number of residues which have alternative side chians, and so on.

Thank you.

King regards,
Wenhe

Dear Wenhe,

what you name 'general' may in fact be quite specific and hence running
a single program without any options provided is rather unlikely to give
the answers you seek.

moleman2 and other USF utilities (not a ccp4 program) come closest to
what you are looking for, I guess.

Cheers,
Tim

We have been doing a bit of this using a simple program under Linux - pdbskim.
A linux binary available on request. Very simple output though, focused on infromation on occ, Bs alternatives, etc to help make decisions during structure refinement.

There are tools to do this - eg REFMAC will tell you no of residues and atoms. PDBSET baverage/ rwcontents etc all offer bits of info, but i guess it would be useful to have a more organised report..
