Hi,

I am trying to build a monomer, using Monomer Library Sketcher, which
has an arsenic attached to an aromatic ring. When I try to create library description the task fails every time with the error message:

WARNING : monomer:PAS      - has the minimal description.
 WARNING: there is not metal chirality for:AS7
 WARNING :          /subroutine CALC_VOBSN/

/home/lparker/lib_stuff/PAS_libcheck.pdb
has failed with error message
Last system error message: No such file or directory
refmac5:  Cannot find input file

If, however, I build the same structure substituting the As for a Carbon
Ii have no troubles at all, this is also the case if I attempt to build a monomer with an As attached to a non-aromatic 6-membered ring. Does
anyone have any suggestions as to how I can build my monomer??

Cheers,

Lorien
