Yup, that took care of it, it works now. Thanks Tom! Lars On Mar 7, 2019, at 3:12 PM, Tom Goddard <goddard@sonic.net<mailto:goddard@sonic.net>> wrote: Oops. Should be v.new_region(ijk_step = (1,1,1), adjust_step = False) Chimera automatically adjust the step size to stay within a maximum total number of voxels. The adjust_step = False means not to do that automatic changing of the specified step.

My implementation was as follows and did not change anything.

May I also ask how to set the ’step’ property value from the volume viewer GUI pop-up from a script?

You would loop through all volume models with something like: from chimera import openModels from VolumeViewer import Volume for vol in openModels.list(modelTypes=[Volume]): print “%d.%d %s” % (vol.id<http://vol.id/>, vol.subid, vol.name) We realize the programmer documentation isn’t great. What little we have you can find here: https://www.cgl.ucsf.edu/chimera/docs/ProgrammersGuide/index.html . One of our objectives for ChimeraX is much better programmer documentation. —Eric Eric Pettersen UCSF Computer Graphics Lab On Mar 6, 2019, at 10:40 AM, Lars Hangartner <lhangart@scripps.edu<mailto:lhangart@scripps.edu>> wrote: Hi guys, I am desperately looking to get the model_id / model name from all open volume objects. I have tried openModel.list()[0].model_id in many iterations but no success… I would like to iterate through models and identify the resampled ones. Can anybody help? Thanks, Lars P.S: API documentation would really be helpful. _______________________________________________ Chimera-dev mailing list Chimera-dev@cgl.ucsf.edu<mailto:Chimera-dev@cgl.ucsf.edu> http://plato.cgl.ucsf.edu/mailman/listinfo/chimera-dev _______________________________________________ Chimera-dev mailing list Chimera-dev@cgl.ucsf.edu<mailto:Chimera-dev@cgl.ucsf.edu> http://plato.cgl.ucsf.edu/mailman/listinfo/chimera-dev
