[ccp4bb] orthogonal limits of a protein

2010-03-24 Thread Francois Berenger
Hello, Is there a ccp4 tool to find automatically the smallest virtual orthogonal box that contain a given PDB ? Even if your favorite tool is not part of ccp4, I would be happy to know about it. ;) Thanks, Francois.

As I recently learnt from Andy Arvai, the -nopixmap is not needed if the (free) NX server has AGENT_EXTRA_OPTIONS_X=-defer 0 in its node.conf . I like this a lot because I tend to forget about the -nopixmap option, _and_ it does not work for the zoom window. HTH, Kay Am 20:59, schrieb

Strictly speaking even Tim's solution may not give the true 'smallest box', by which I assume is meant 'minimal volume box'. I suspect moleman does this calculation (my apologies to Gerard if I'm wrong!) by determining the axes of inertia, then rotating the molecule by the matrix of eigenvectors

There are three diastereomers, two of which I think work. The meso compound, however supposedly does not freeze clear. Hampton sells two of these in their kit, but doesn't specify the stereochemistry of one of them. http://hamptonresearch.com/product_detail.aspx?cid=30sid=189pid=30 William Ho

I have a program that would calculate the limits of the protein along it's axes of inertia (besides doing many other things). If you are interested, please let me know. Thanks Abhinav j...@ssrl Phone: (650) 926-2992 Fax: (650) 926-3292 Francois Berenger wrote: Hello, Is there a ccp4

[ccp4bb] Full B Factor

How do I convert the B-factors from my final structure to full B factors if I did not use TLS refinement? I have been refining isotropic B-factors. Do I switch to overall B-factor refinement, do something else, or have I missed the point altogether? It may be a dumb question but best to be

thanks so far for sharing your experience with Butanediol. But is it important to use a specific enantiomer ? Are you all only using 2R3R- Butanediol which is quite expensive ? Sigma Cat. # 18970 2,3-Butanediol puriss., mixture of racemic and meso forms, ≥99.0% (GC) (Fluka) works well and

Dear Paul, You can also use idiffdisp, which might do what you want. See http://ccp4wiki.org/~ccp4wiki/wiki/index.php?title=CCP4i_diffraction_image_display_%28idiffdisp%29 http://ccp4wiki.org/~ccp4wiki/wiki/index.php?title=CCP4i_diffraction_image_display_%28idiffdisp%29 Cheers David

Hi Daniel, How do I convert the B-factors from my final structure to full B factors if I did not use TLS refinement? a non-ccp4 tool: if you have PHENIX installed then: 1) if your PDB file has TLS matrices in its header and residual B-factors in ATOM records, then: phenix.tls model.pdb
