[chimerax-users] Re: ISOLDE messes with view?

Hi Alexis, The definition of zoom is not the same for perspective projection and orthographic projection, so it doesn't make sense to restore the perspective zoom in orthographic mode. ChimeraX could guess what depth you want the scaling to match. That will lead to confusion since the appearance will not be the same as when the view was named unless the camera mode is switched.

Hi Tom, Tristan,

Thanks - that sounds like it could indeed be the root cause.

Tom, I'm not sure what the correct behavior should be. One possible complication I see is with the fly command - what would the expected behavior be there? I guess I would expect the zoom to be restored by view and fly, but the camera mode to not be changed by either of these commands.

Cheers, Alexis

Hi Tristan, Alexis,

Testing shows that naming a view using the default perspective camera ("view name v1") and then using "camera ortho" and then restoring the view ("view v1") does not restore the zoom. So that is probably the problem. I'm not sure if the view command should be switching the camera modes. Maybe it should.

The following alias should let you set everything back to factory default after you’ve used ISOLDE:

alias clipperOff camera mono;cofr front showPivot false;mousemode left select control; mousemode left none control shift; mousemode middle none control; mousemode wheel zoom; mousemode right none shift; mousemode wheel none control; mousemode wheel none alt;mousemode wheel none shift; clip off

I *think* this is probably because Clipper sets the camera to orthographic on first initialisation. I can’t recall doing much more complex than that, but I can check… possibly its custom zoom mouse mode *might* be the culprit.

Hello,

I've just noticed that the view command doesn't behave as expected after I have started ISOLDE.

Specifically, if I save a view ("view name view1") and later try to restore it ("view view1"), it will get me back to the correct orientation of view1 but the zoom will not be restored.

I assume ISOLDE is changing a setting under the hood. Is there some way to make ISOLDE play nicely with "view"? Right now my only workaround is to quit ChimeraX and start again front he beginning, without launching ISOLDE.
