Hi Swanand,

yes:

iotbx.show_distances your.pdb > all_distances

will show long list of all distances between pairs including symmetry related. For symmetry related it will also show the symmetry operator the relates involved atoms.

Look implementation for underlying code.

Type iotbx.show_distances without arguments to see all options.

Hi All,

I am sure this has been asked and answered a lot of times...

Is there a python script somewhere that reads a mmcif file and for any residue in it, returns a list of residues within a certain distance of it. And it returns any symmetry-related copies of residues too within that distance.

Any pointer greatly appreciated.

Thanks,
Swanand
