Hello.

I'd like to generate a map appropriate for viewing in PyMOL, using a model and structure factors downloaded from the PDB. But I'm unable to do so, and perhaps you can help me figure out what I might be doing wrong: 

To generate the map, I did the following using the phenix GUI (version 1.9-1692): 

1. I used Reflection tools > Import CIF structure factors to convert the .cif format structure factors for PDB id 1J8U to an mtz file.

2. Then, to configure the job to generate the CCP4 map, I loaded this mtz file, but when I did that I got the following error:

I went through the same steps again for two other PDB ids, this time generating the mtz file by either letting phenix do it from a PDB id, or by supplying the tool with both a .cif file with structure factors and a pdb model file. I get the same error.
