volume eraser and imod isosurface
by Wouter Van Putte 06 Jan '16

06 Jan '16

Dear, I would like to use chimera for removing some densities manually of an isosurface generated with imod. I've loaded the map/model (.mod) and already used the function 'hide dust' to remove most of the noise. I now would like to use 'volume eraser' to remove the other noise manually. This however doesn't work, probably due to the file format (.mod). I thought saving in another file format would help, but it gave me errors when opening the file. How should I proceed? best wishes, Wouter

Drawing shapes given coordinates
by Rebecca Swett 05 Jan '16

05 Jan '16

Hi all, I'm trying to add some 3d shapes to a visualization. I was wondering if it would be possible to draw either a cylinder or tube given starting and ending coordinates rather than atom names/numbers or centroid? For example, if I had this coordinate pair: 6.17 1.10 -15.33 20.82 -0.70 -8.39 What would be the best way to go about drawing a line of some sort between those two points? I have dozens of pairs of coordinates so something command line would be ideal. Cheers, Rebecca This email message and any attachments are confidential and intended for use by the addressee(s) only.

Identify hinges and rigid groups using Morph Conformations?
by Oliver Clarke 04 Jan '16

04 Jan '16

Hi, I gather from reading the documentation for “Morph Conformations” (https://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/morph/morph.html) that Chimera identifies hinge regions and rigid groups as part of the procedure (as per http://nar.oxfordjournals.org/content/28/8/1665.long). Would it be possible to expose these to the user (or maybe this is already possible?), such that one can color/label the hinges and rigid entities as desired? This would be helpful for visual simplification of complex conformational changes. Cheers, Oliver.
