Re: [COOT] Color chains or turn on environmental distances between molecules
I believe "bonds colour by chain" option in display manager does color chains differently.

[COOT] sphere refine
Is there currently a way to auto-run the sphere refine on full sequence (similarly to stepped refine option, preferably with an option to enforce Ramachandran)? If not, are there plans to add such feature? Is there some fundamental objection to such feature?

Re: [COOT] pdb file problem with duplicate amino acid
Thanks - sorry I should have searched the archives first. As a suggestion, could you alter the warning text to include the fix decription (i.e. "include this in your .coot.py)? This way users would know what to do right away.

[COOT] pdb file problem with duplicate amino acid
Whatever the rationale was, there is a structure in the PDB that has alternate conformer of a residue listed with different residue type - A is arginine and B is glutamine. Coot fails to load the model complaining in the command window WARNING:: Error reading small-molecule cif "/home/epo/coot/foo.pdb" > There was an error reading /home/epo/coot/foo.pdb. > ERROR 42 READ: Duplicate sequence number and insertion code. > LINE #1571 > ATOM 1666 N BGLN B 93 24.448 28.340 -33.325 0.50 > 9.34 N > > No Spacegroup found for this PDB file > There was a coordinates read error > One way to deal with it is to take the second conformer and manually add a sequence modifier (make it 93A), and that pdb file loads just fine. This is observed with Coot-0.8.8-pre, rev.6506. This is only a minor nuisance, of course, so I completely understand if no fix is made to load such strange models. Cheers, Ed. --- Coot verendus est
Re: [COOT] Coot "open file" dialogue connection to CCP4
Resetting $HOME won't work for me personally since I do have some custom stuff in ~/.coot.py. I could symlink it to the coot home folder, of course. Hopefully, no other problems pop up and coot does not rely on some configuration file stored in the actual home folder. Making .CCP4 folder unreadable is a better hack for sure - this way one can't open CCP4 accidentally and overwrite the database. Creating a separate account to just run coot (ideally configured to allow su without a password) is another possibility. None of this is ideal, of course. Adding option to coot preferences to disable CCP4 folders is. Probably the non-ugly one-way hack is to put return statement at the top of add_ccp4i_projects_to_optionmenu in c-interface-gui.cc and compile from source.

[COOT] fresh coot misbehaves? (well, not really)
I had an opportunity to build coot executable on a fresh ubuntu box. It compiles fine after you install few dependencies but I noticed the following: 1) it seems that coot won't work without CCP4. It won't load mtz files - complained that the map file wasn't proper format. 2) Even after I installed CCP4, it wants me to have ccp4 configuration script sourced or it won't refine even amino acids in real space. I was under impression that in the past standard amino acids were accessible even if ccp4 monomer libraries cannot be reached. Maybe it changed. None of this is a big deal, just surprising. Obviously, having coot installed without ccp4 is a bit unusual, although having a standalone coot (say, for teaching purposes on a flash drive) is not completely unimaginable.

Re: [COOT] Coot "open file" dialogue connection to CCP4
This is an ugly hack, but here goes: 1. Prior to opening coot, rename you .CCP4 folder. (bash: mv .CCP4 .CCP4_hidden) 2. Open coot. Do what you need to do. 3. Close coot. 4. Restore .CCP4 folder (bash: mv .CCP4_hidden .CCP4) You can make a shortcut by putting this into your .bashrc coot_no_ccp4_folders () { mv ~/.CCP4 ~/.CCP4_hidden coot mv ~/.CCP4_hidden ~/.CCP4 } Use with caution - if you mess up, you may lose all your CCP4 configuration. This is not very convenient, since you cannot use ccp4 in the meantime - I checked and the list of CCP4 folders does come up if you restore the CCP4 database folder while coot is still running. If you do use CCP4 in the meantime, it will create an empty database, which is obviously not what you want. If you are into hacking the coot source (with proper apologies to Paul), then find src/graphics-info.cc file in your coot source, go to ccp4_defs_file_name method and mess with it in an obvious way - it returns the path to your CCP4 database folder, so just change it to something non-existent. Compile custom coot binaries as usual and see what happens. It might break spectacularly in case this method is used in a way other than getting the CCP4 project folders listed in the file opening dialog. Or it may behave exactly as you wish. Live dangerously :) My complaint about this feature is that it lists folder names, not project names (I realize this might require customization of the dialog, so not necessarily easy to fix). My habit is to create CCP4 projects as need and name corresponding folders ccp4 inside another folder that holds the data. As a result, I end up with a bunch of "ccp4" items in the list of folders, which is unusable (I think it shows the full path if you hover over the name, but that's not too helpful if you are looking for a particular project. Of course, I should simply name folders in a more comprehensible way. HTH, Ed.

Re: [COOT] Add OXT broken?
Funny, but your email consistently crashes my Evolution Email client. Not a coot problem, I presume :) Cheers, Ed. When I try to add an OXT to my model, coot crashes. Specifically, when I try to change the chain from the list in the popup window (below), it hangs then completely crashes. I'm on an intel mac running 10.6.8, with Coot 0.7-pre-1 (revision 3628). Bug?
