Checks if planar groups are planar enough.


The Cambridge small molecule database was analysed and a set of ideal planarities was derived. This server checks if all groups that are supposed to be planar are indeed planar enough. Four sigma deviations are listed.

We could not find enough nucleic acids to do the same for these those. So, in case your PDB file contains nucleic acids, un uncallibrated validation (read: comparison with gambled standard data) is performed on them.

Either Choose a pdb-file,
Or Choose your own file

See our validation related articles for more background details regarding the validation servers. See also the WWW based validation explanation. If you have detected any error, or have any question or suggestion, please send an Email to Gert Vriend.
