dear all,

I have segmented different parts of my tomogram using different software packages.  One outputs an MRC file which I Can display as either volume or surface.  The other is exported from Dragonfly and I am unable to figure out how to export MRC so I have tried STL and OBJ.  STL/OBJ will display in ChimeraX, but then if I try to load in the other segmentation MRC then the STL/OBJ will disappear.  I cannot view both simultaneously.  If I hide the mrc and "view all" then I can view the object.  Conversely, if I hide the object and "view all" I can see the MRC.   Any help would be appreciated.  Is there any way to convert obj/stl to an mrc?  

thanks!
