[Chimera-users] lost focus wile rotating molecules after zoom-in

[Sheng-Hung Wang]

Dear Tom,

I see! I greatly appreciate Chimera team!



> Hi Shawn,
> 
>   Your case #1 is normal Chimera 1.4 behavior as
> described in the documentation:
> 
> http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/sideview.html#rotation
> 
> "center of rotation method:
> 
> front center (default) - when the view is zoomed out,
> behaves like center of models; when the view is zoomed in on
> parts of items, behaves like center of view, except the
> center of rotation depth (Z-coordinate) is set to that of
> the frontmost displayed unclipped atom whose VDW sphere
> intercepts a line perpendicular to the screen in the window
> center. The center is not updated when only rotations are
> performed. "
> 
> If you prefer the Chimera 1.3 behavior where rotation is
> about the center of the molecule even when you are zoomed in
> then set the rotation center to "center of models" and save
> that setting for future sessions.  Details are on the
> above web page.
> 
>   For case #2 that is a bug with the Model Panel
> dialog Focus button in Chimera 1.4 and I'll look at it
> shortly.

> I'm using ver. 1.4 (build 29251) Chimera running on CentOS
> 5.x x86_64 Linux. I make a description here first and then I
> will try to report it through Help dialog. The term "lost
> focus" I have mentioned means that the centroid of molecule
> do not always be kept at the center of window. 
> > Condition #1.  Open a protein structure, and then
> click FOCUS from ACTIONS of the main menu without selecting
> anything. After doing zoom-in, rotation, and then zoom-out,
> the position of molecular centroid migrated.
> > 
> > Condition #2. Open a protein and it's ligand in the
> same session followed by opening MODEL PANEL dialog.
> Selecting ligand and then focusing it from MODEL PANEL
> dialog, you will find Chimera do not focus the ligand once
> molecules are rotated. However, it works fine while
> selection and focusing are done through main menu.
