Dear All,
I am having trouble with refmac dictionaries when refining a
structure that contains an iodine ion.
the PDB entry should be correct and according to the convention
(water added for comparison):
-----
ATOM 2838 O HOH W 102 6.018 39.720 31.127 1.00
21.43 O
ATOM 2839 I I B 1 19.956 22.770 18.597 1.00
30.00 I

I figured that it tries to read the wrong dictionary (although the
correct one ( I.cif) is present in the same directory). Explicitly
supplying I.cif with a LIB_IN card does not help
thanks for your help

PS:probably this has been on the bb in the past, but I could not
dig it out
