Dear Amber users:

We're back to trying to use carnal and we could use some help. We are trying to write out a normal vector to a plane described by three atoms (#s 256-258) in a trajectory into a CRD file (or PDB). Our carnal input file (analin) looks like what is below. All that gets written to the file cno2.pdb is CARNAL dump. So, it looks like we've screwed up something between the DECLARE and OUTPUT statements so that there is nothing to write. We've played around a bit with this but other that generating errors, no luck. Any suggestions. Thanks.

  PARM p1;
  STREAM s1 tat5m_md_nowatNA.traj;
  COORD crd cno2.pdb CRD;
  PLANE pn1 256 257 258;
  COORD crd s1 SELECT (256-258);
