[Chimera-users] volume viewer - planes

[Tom Goddard]

Hi Michael,

  It would be nice if moving the slider updated the shown plane for all the volumes.  I couldn’t think of a trick to do that.  But here is a Python script syncregion.py that does it.  You open this file in Chimera when you have your volumes open and whenever the active one (one highlighted in volume viewer dialog) changes its displayed region, the other are updated to use the same region.

So you’d have to click on one histogram to make that set “active” and connected to the slider, then click the other histogram to connect the other set to the slider instead.

I guess the drawback is that the indices would have to be the same for the different datasets.

Often I want to compare different processing or filtering of the same dataset. When I load several datasets, all the visualization parameters are set individually. Normally this is good, for example in setting different colors, but for Planes it's problematic. In order to switch among the various representations and see the same section of the volume I have to scan them individually, and when two are visible I can move only one. Is there a way to link the Planes among the maps? Perhaps there's a command line trick?
