Dear coot users,
I've tried to auto-open several MTZ files without success.
The MTZ files were produced using REFMAC5 (restrain refinement). After loading
the PDB file in coot (successfully) I tried to auto-open the related MTZ file
but coot crushed giving the following message:
Number of OBSERVED reflections: 8194

This is not helpful.
Please turn on core dumps before sending a crash report.
This should not be a problem related to the coot version. I had the same error
message from coot using both the 0.7-pre version (installed using fink) and the
latest stable release (0.6.2 version, installed using the pkg-coot installer,
the dmg was downloaded from the ccp4 web site). Moreover this is not a problem
related to a particular MTZ file: I had the same error message testing 3
different MTZ files from 3 independent projects.
I'm using as operative system a Mac OS X 10.6.8 on a MacBook Pro.
Could anyone please give me suggestions how to fix the problem?
Thanks a lot in advance.
Best regards
Stefano
