Hi Mike, That error typically means that either there are bad bonds in the molecule (which could be the fault of Chimera or a problem with the input) or that a non-sp2 atom has been wrongly assigned an sp2 type (usually Chimera's fault alone). Could you provide the structure that elicits the error so that I can investigate? Thanks. --Eric Eric Pettersen UCSF Computer Graphics Lab pett@cgl.ucsf.edu http://www.cgl.ucsf.edu On Jul 13, 2007, at 5:08 AM, Mike Gretes wrote:
Hello,
When trying to calculate hydrogen bonding between two molecules, I get the error:
"ValueError: More than 2 coplanar positions specified!"
I have successfully calculated h-bonding between two other similar molecules, so I'm not sure what the problem is (I have no alternate conformations or anything weird in the PDB files I don't think... is there anything that usually triggers this error?)
thanks!
mike
