Re: [phenixbb] segmented rigid body refinement

Hi Gino, you could use phenix.find_tls_groups but the tool requires meaningfully refined B-factors and more or less good geometry so the secondary structure can be identified automatically. If this is your case then phenix.find_tls_groups might work for you. Pavel On 7/12/12 9:33 AM, Gino Cingolani wrote:

The latter....something more analytical to split individual chains into smaller groups (e.g. like to define tls groups).

Thanks,

Gino

I'm refining a large oligomeric structure at low res (~6A). I'd like to define groups to use for 'segmented rigid body refinement'. Is there any rational way to define 'segments'? My macromolecule is already an oligomer on its own, so, intuitively, each protomer is a segment.

Not sure I understand the question - do you mean you want to split the individual chains into smaller groups, and you're looking for an analytical method for determining these groups?
