[ccp4bb] Docking models into low-res SAD map - summary

2013-09-23 Thread Oliver Clarke
Many thanks for all the replies - I haven't yet tried all of them, but they all look worth following up on, much food for thought here: * Several people suggested SITUS COLORES, which I shall certainly try and had not heard of until now. * The program ESSENS, from the Uppsala software factory,

When we have needed to do something like this, the following procedure has worked pretty well for us: 1. Define the volume containing the density into which a model should be docked (most easily as atoms in a PDB file specifying the centres of spheres), then get structure factors corresponding

Hi Oliver, Use CHIMERA- http://www.cgl.ucsf.edu/chimera/ There are video tutorials for docking- http://www.cgl.ucsf.edu/chimera/videodoc/videodoc.html This is a very good package. While I have used Situs colores, I find this package more versatile and useful. You can also use Pymol (but I

Hi Folmer, As I said- I think its not free any more is indicative that I am not sure of its status. In addition to that I do not use Pymol much. Thanks for the correction. Best Dr. Anindito Sen (Ph.D) Department of Cell Biology Anatomy Graduate School of Medicine University of Tokyo

Hi Oliver a few years ago I used the ccp4 FFFEAR program from Kevin Cowtan for this sort of domain search. It was very good but also quite labour-intensive. I have not followed up since to see if it was updated or the functionality was included in Buccaneer. cheers Martyn

Perhaps Situs colores would be useful. We use it to dock models into SAXS maps. http://situs.biomachina.org/fguide.html Sent from Jack's iPad On Sep 18, 2013, at 5:48 PM, Oliver Clarke olibcla...@gmail.com wrote: Hi all, Can anyone recommend software to dock previously solved domains

Another vote for Situs colores - we've had very good luck with using it to dock domain structures into low resolution multi-crystal SAD maps. Pete Oliver Clarke wrote: Hi all, Can anyone recommend software to dock previously solved domains into a (very) low-resolution experimentally phased

Hi all, Can anyone recommend software to dock previously solved domains into a (very) low-resolution experimentally phased map? I am working on a rather marginal case where this would be useful - very large assembly (500kDA per ASU), native goes to 6.9A, and the best derivative goes to 8A
