Dear phenix list, I am wanting to model a poly-proline structure. I created the file in PyMOL, saved it as a pdb, and then tried to regularize it with: phenix.pdbtools polypro.pdb --geometry_regularization However the program reported (snipped to the last few lines): ATOM 63 CD PRO 6 -3.290 3.487 -2.968 1.00 0.00 C ATOM 69 2HD PRO 6 -2.824 2.626 -3.453 1.00 0.00 H Distance model: 1.09209 (ideal: 0.97) ATOM 63 CD PRO 6 -3.290 3.487 -2.968 1.00 0.00 C ATOM 70 3HD PRO 6 -4.165 3.171 -2.396 1.00 0.00 H Distance model: 1.44721 (ideal: 1.473) ATOM 57 N PRO 6 -2.321 4.145 -2.118 1.00 0.00 N ATOM 63 CD PRO 6 -3.290 3.487 -2.968 1.00 0.00 C Distance model: 1.53855 (ideal: 1.525) ATOM 58 CA PRO 6 -1.810 5.407 -2.632 1.00 0.00 C ATOM 59 C PRO 6 -2.332 6.603 -1.817 1.00 0.00 C Distance model: 1.23088 (ideal: 1.231) ATOM 59 C PRO 6 -2.332 6.603 -1.817 1.00 0.00 C ATOM 60 O PRO 6 -3.080 6.424 -0.856 1.00 0.00 O Sorry: Number of bonds with excessive lengths: 74 I thought the whole purpose of geometry regularization was to get rid of excessive lengths, not just tell me they are there!! How do I get the program to really regularize my geometry? Thanks, Simon
Hi Simon, there must be something weird in your file... Could you please send me it? Pavel. On 10/21/2008 3:01 AM, Simon Kolstoe wrote:

I've noticed this error too. It occured when I was missing a CRYST 1
line in my PDB. I'm not sure if just any old CRYST 1 line will work,
but if you generate one that has a very large P1 cell, your error
should go away.

Thanks for the tip. A CRYST1 card solved the problem. Simon On 21 Oct 2008, at 16:08, James Fraser wrote:
