Dear Elaine: 
           Thank you very much. The red model is the Amira segmentation file, I changed it to mrc file. I want to fit the model  with density map. I don’t know why I cannot save the model as map.

> but there isn’t a tool to fit a map to a surface… it’s just an empty shell. Maybe you could somehow first make a new map based on that surface (e.g. 1 inside 0 outside) and then try to fit to that, but I don’t know if that really makes sense or would even work.
