Save PDB and Map before fitting
by Pablo Solar Rodríguez 14 May '17

14 May '17

Hi all, Hope everything is going fine! In my plugin, it is necessary to save the PDB and the map (ccp4) to disk before the exhaustive fitting process is executed. Is there any simple and efficient way of doing this? I've checked the scripts and haven't found anything about this and I wouldn't like to have to replicate the code from the Chimera source (OpenSave and the relative to maps). This question is quite related to the previous one I made about copying a molecule. Thank you all in advance and kind regards from Spain.

Get values from other chimera dialogs
by Pablo Solar Rodríguez 08 May '17

08 May '17

Hello everyone! I feel you will get tired of me asking so many questions hehe Anyway, I continue developing my plugin and I'd like to know if there's any way to get values from other chimera dialogs although they are not open. For example, when my map is loaded I need the values, from the Volume Viewer, of the voxel size (in Coordinates panel) and the cutoff, but I didn't find how to get them and I really don't know if this is possible or not. Thank you in advance and, as usual, kind regards! Pablo.

Hi, I'm part of the UWP Open Source Community (https://github.com/UWP-Open-Source-Community). Our intent is to take Win32 Open Source applications and convert them into UWP apps through the Windows Bridge (Project Centennial). We like your app and that's why we decided to convert it. In case you would like to take charge of this app and publish it yourself on the store (make us very pleased) contact us the first possible please! Otherwise, we may be responsible for publishing your app. If you do not want to take over the publication on the Store, can you give us permission to do so? Sorry for my poor English. Thanks for your help. Regards, Marco Leonardi

Hi Matt, There is some information about how to install Python packages with Chimera in the programming FAQ https://www.cgl.ucsf.edu/chimera/docs/ProgrammersGuide/faq.html#q3b but I believe Eric here said the suggested approach to doing pip install no longer works. A more hacky approach is to simply copy site-packages/Mido (or whatever the module is called) from your system installed version into the Chimera Python site-packages (in chimera/lib/python2.7/site-packages or Chimera.app/Contents/Resources/lib/python2.7/site-packages on Mac).

Qt5 is the window toolkit used by ChimeraX and it controls the receiving of events from devices. I don’t know of an adequate Qt / MIDI library exists.

We don’t have volume erase in ChimeraX yet. Probably not coming for at least 6 months other new tools and more commonly used capabilities will come first. But when it does arrive allowing a box eraser instead of a sphere should be easy.

Volume eraser shows a sphere. There is no code to show a box.

Hi Matt, To get the current region and step for a volume ijk_min, ijk_max, ijk_step = v.region To avoid having the step adjust automatically in the new_region() call use new_region(..., adjust_step = False) Chimera adusts the step to show no more than some specified number of grid points (e.g. 2 million) and this parameter is v.rendering_options.voxel_limit = 1 # In millions of voxels v.rendering_options.limit_voxel_count = True # Whether to auto-adjust step These options are also present in the Volume Viewer dialog, menu Features / Data Display Options.

(Smart) Copy Molecule to ModelPanel after fitting in plugin
by Pablo Solar Rodríguez 10 Apr '17

10 Apr '17

Hi all! Hope everything is ok! :) I would like to know if there is any smart way to copy/duplicate a Molecule directly to the Model Panel. The plugin I am developing for an exahustive fitting generates N solutions on the same opened Molecule. In this situation, when the process has finished, the user can choose a solution and the Molecule rotates and translates to the associated position. That is, N different positions for each solutions. What I want is to let the user be able to "save" the solution it wants and show it in the Model Panel. An example: _I've got a chainH.pdb and a ccp4 map. After my exhaustive fitting process, 10 solutions are generated, so chainH can be moved into 10 different positions. Next step is that if user choses the solution number 7, chainH will move and rotate to that 7 solution and the user can save this into the Model Panel with solution7_chainH.pdb name_. Is there a simple way to do this? I've checked the Copy/Combine source code (http://plato.cgl.ucsf.edu/trac/chimera/browser/trunk/libs/Combine [1]) but I want to know if there is a better way and not to "replicate" this code.

Yes. In fact all that is done with the new_region() routine. (set step with the ijk_step argument, eg. ijk_step = (2,2,2). Set plane number by setting ijk_min, ijk_max to show one plane).
