Hi there, my name is Jose Alirio Mendoza. Currently, I am carrying out my PHD thesis in which I am using the chimera program to show the tomography results. Nevertheless, I am being presented some problems when trying to measure my particle in Chimera. The file of my product is “mrc” and I have been investigating about chimera usage where I have realized that the file must be “pdb” for the program to recognize it. I do not really know how to convert my molecule to the required file, and I guess that is the problem by which I cannot measure the distance of my particle. When I click “tools – structure analysis – distance” it does not appear the code of my molecule as in picture below

This is my particle and what I get when using the tool for measuring. I have other three tomography for one publication.

There is not any code in the tool square and that is why I guess to no be able to measure the particle.

Other tool I tried to use is the scale bar, however the value of it is not according to my calibration.

How may I change that calibration?

In our research group we want the publish the articles citing chimera as visualization tool so we would really appreciate your help.


Here is attached the file we have worked in chimera.
