Dear all,

I want to find all the atomic positions in a pdb file, not just the symmetry 
unique ones. I think the flag to do this is --fillUC, but it seems to have 
problems with my PDB file, because I get the message:

*** Open Babel Warning  in Do
   Cannot fill unit cell without spacegroup information !

My command is:
  babel --fillUC strict csd_manthr01.pdb new.cif

(I actually want a CASTEP cell file, but I know how to get this from cif). The 
PDB file comes from the Cambridge Structural Database, and the first few lines 
are:

HEADER    CSD
COMPND    MANTHR01
AUTHOR    Generated by a CDS Utility
CRYST1    8.909   14.625    8.060  90.00  96.53  90.00 P21/c       14
ATOM      1  C   MOL     8       3.618   5.399   1.991  1.00  0.00
...

The space group information is presumably the P21/c in the CRYST1 line. Is the 
file wrong, can babel not handle it correctly, or do I need a different flag?

Thanks in advance,

   Herbert
