An Email from Evan on Pymol newgroup had the following exchange regarding the slice_map function

Hi,

I'm trying to use the "slice" function on the map of an EM reconstruction,
but can't find any documentation or list comments.

"Slice" makes a thin section of the map and colors it red (empty) to blue
(high density). I've figured out how to move the map through the slice with
the mouse (Shift, Wheel) but can't see how to do this with commands.

Also, is there a way to rotate the slice, so I can see it from an angle?

Finally, what is the meaning or use of "tracking on/off", "height map
on/off", and "dynamic grid on/off"?

Thanks,
Evan Sadler

To Which Warren replies:

 

 

Evan,

By default, the slice tracks with the 3D center of the camera view.

If you turn off tracking, then you can rotate the camera independently of
the slice.  Then, with the mouse in 3-button-editing mode you can manipulate
it with shift-click-and-drag actions.

Height map is self-explanatory (once tracking is off...).

Dynamic grid can improve performance by reducing sampling to only what is
needed onscreen.

Cheers,
Warren
