[Chimera-users] How to fit an atomic model into a topographic height volume

[Lee, Yun-Tzai (NIH/NCI) [F]]

Dear Chimera developers,
I am a research fellow who works at Frederick Biophysics Laboratory and working on an image processing project.
I used Chimera to generate a topographic height volume data from a single plane image.
You can find the attached file and use a command following to generate the topographic surface.
% topography #0 height -40 smoothingIteration 5
But there is no option for me to fit the atomic model into the surface height volume by using Fit in Map tools.

Can someone help me figure out what’s the issue? Is that possible to fit an atomic model into a height volume created by a single plane image or just simply need multiple planes?
Thanks in advance.

Best,
Yun-Tzai
