Hello Everyone,

I’m having trouble opening the map file generated by phenix.fem in coot. Each time I try and load the .mtz file the follow error occurs ‘Failed to find any suitable F/phi columns in the MTZ file’.

Dumping the mtz file I can see:

Col Sort    Min    Max    Num      %     Mean     Mean   Resolution   Type Column

num order               Missing complete          abs.   Low    High       label

   1 NONE     0      33      0  100.00     12.1     12.1 114.15   3.31   H  H

   2 NONE     0      33      0  100.00     12.8     12.8 114.15   3.31   H  K

   3 NONE     0     137      0  100.00     51.4     51.4 114.15   3.31   H  L

   4 NONE    0.0 10551.1 22963   71.24   406.13   406.13  39.60   3.31   F  2mFoDFc

   5 NONE -180.0   180.0 22963   71.24     0.98    89.81  39.60   3.31   P  PHI2mFoDFc

   6 NONE    5.2 51589.8     0  100.00  1602.72  1602.72 114.15   3.31   F  FEM

   7 NONE -180.0   180.0     0  100.00     0.32    89.74 114.15   3.31   P  PHIFEM

If someone could help me to rename these columns to a coot friendly format so that I would be greatly appreciative.

Best,

Parker
