Hi Bryan, there is a specific tool to do this Just type in the command line: phenix.cif_as_mtz and hit Enter. This will give you the instructions about how to use it. Please let me know if you have any questions or problems using it. Pavel. On 9/3/09 11:06 AM, Bryan W. Lepore wrote:

i obtained a recent .cif from the PDB, then run :

phenix.reflection_file_converter --mtz=output.mtz test.cif

file_name: test.cif file_type: None

No reflection data found in input file.

.... not sure where to go from here (a clip of the file is below, hope not too much) - i know i can run ccp4:cif2mtz, but are .cif part of phenix.reflection_file_converter?
