This small jiffy is temporary solution of the problem of
the atom recognition by the program(s) refmac/libcheck. When
atoms have four character name and first character is not
for atom name then refmac/libcheck have difficulty to recognise
atom and element names. In these cases element names must be present 
in the input pdb file. Residues likely to have this problem are
   NAD, NAP, NDP, COA, FAD, AP5, CAC

How to use this jiffy. Do

f77 -o add_element add_element.f

then use

wherever_add_element/add_element
input_file
output_file


Then output file should be ready to use in the refmac.
