Re: [COOT] fractional coordinates

Hi Tim, For your second question, I think the function map_peaks_near_point_from_list() would do something similar to what you want. If you call it as closePoints = map_peaks_near_point_from_list(mapNum, pointList, x, y, z, radius) then all the points in pointList will have symmetry

Re: [COOT] Incorrect atom labels when building ideal RNA helices.

Francis, do you have CCP4 installed on this machine as well? What version is it? Also, what's the naming on the newly created ideal RNA. Is it using * or ' for prime? If your installation of CCP4 isn't the newest version (6.2), that may be causing your problem. Starting with rev

Using G instead of Gr is part of the new PDB3 standard. If I remember correctly, a DNA G is now called DG, and I think CNS still uses GUA. Regardless, it sounds like your distribution of Coot may still be using the old-style monomer libraries. The status message you pasted below

set_refinement_immediate_replacement(1) should stop Coot from prompting you. I think you'll still need to call accept_regularizement() after you run the refinement to actually accept the results. In case your interested, set_refinement_immediate_replacement(0) will set it back, and

[COOT] New Coot plugin for RNA building

2011-03-31 Thread Kevin Keating
I've just released a new Coot plugin to help with building RNA structure, so I wanted to make a quick announcement to the mailing list for any interested RNA crystallographers. The plugin, named RCrane, is free for use and can be downloaded from

Re: [COOT] COOT for low resolution

2011-03-18 Thread Kevin Keating
Lowering the matrix term further might help. I've set it to 10 when working with ~3 A RNA maps, so you might want to try values around 5-10. If you're using the most recent build of Coot (revision 3440), you could also try using harmonic restraints. These allow an atom to move slightly
