converting mmcif to mtz failure

From: Jacob Keller
Date: 6 September 2011 22:34

Dear Crystallographers,

in trying to convert a mmcif to mtz, I get the logfile below. I looked
in the directory, and there is a file cf_mm.dic, but this is
presumably not the same as the similar .lib file. Any thoughts about
this? Did the file somehow get lost? Also, I recently did this same
conversion to another file without problems...

Yes, the program does need the (binary) data file cif_mmdic.lib which is
created from the cif_mm.dic file.

This should be in the directory C:\CCP4-Packages\ccp4-6.2.0\lib and NOT
C:\CCP4-Packages\ccp4-6.2.0\lib\data as you have.

Which suggests that the environment variable MMCIFDIC is set wrongly.
And if I look at my windows installation .... mmm yes it is set wrong
and cif2mtz indeed fails. Edit it in system -> advanced -> environment
variables (or whatever ....), restart ccp4i, and voila it works!

So sorry, this looks like a cock-up in the windows distribution :(
