Our volume expert is away right now, but I would suggest using the "Help... Report a Bug" dialog
and attaching an example of a file needed to reproduce this problem. It may be that these files
do not adhere to the MRC format, or at least as Chimera expects it.
Please include your email address in the bugreport if you wish feedback when someone is able
to look at this in more detail.
I see a note in the documentation
that MRC files output by Chimera are in MRC 2000 format, and
"Older MRC-reading programs or programs expecting CCP4 format will read such files
successfully but may not align the data correctly with other data sets."
However, I don't know specifically what subtypes of MRC format are handled on input, or if
some simple editing could solve the problem.
Sorry I don't know more,
