Dear Coot users,

I have been refining the crystal structure of a large assembly which has half a million of atoms. In the PDB, when atom number exceeds 99999, it starts to use letters such as A0000. Everything was fine for phenix and coot to deal with such a structure until recently I tried to refine the TLS parameters. The TLS refinement puts ANISOU record below each ATOM line in the PDB file and when the atom number has 5 digits it concatenates with ANISOU giving something like:

ATOM 99999 O2* Cr A 453 41.217 18.570 115.721 1.00107.41 16S1 O ANISOU99999 O2* Cr A 453 18694 11085 11032 -1586 395 -1101 16S1 O ATOM A0000 C1* Cr A 453 42.986 17.740 114.321 1.00106.92 16S1 C ANISOUA0000 C1* Cr A 453 18592 11040 10992 -1526 256 -1044 16S1 C

When I try to open the PDB file in coot, it gives an error:

ERROR 14 READ: Unmatch in different records for the same atom.
         LINE #200536
ANISOUA0000 C1* Cr A 453 18592 11040 10992 -1526 256 -1044 16S1 C

It looks like coot does not recognize ANISOU followed by a letter without space in between. (ANISOU99999 is fine)

I am not sure if it is a bug of coot or it is inherited from mmdb. I would appreciate it very much if anyone can help me out or give me a clue.


I believe that this is an mmdb issue. I will inform Eugene (if he doesn't already know about and has fixed it already).

Regards,

Paul.
