[Chimera-users] PDB file created by a protein—protien docking tool ZDOCK can not opened by Chimera

[Elaine Meng]

Dear Siyu Zhao,
The file from ZDOCK does not follow the PDB format description because it has extra numbers in the wrong places after the X,Y,Z coordinates. Probably Jmol and DSV are not bothered by those extra numbers, but Chimera does not tolerate them.  If you just remove the columns after the coordinates, the file will display in Chimera.  Below I attached an edited copy of your file which includes only columns 1-54.

ZDOCK output before editing:
ATOM      1  N   LYS A   2      -1.022  -5.354  37.251  4     1 1.63         -0.15
ATOM      2  CA  LYS A   2      -1.230  -4.312  38.301  4     1 2.03          0.10
ATOM      3  C   LYS A   2       0.011  -3.410  38.417  4     0 1.67          0.60
…after editing (OK for Chimera):
ATOM      1  N   LYS A   2      -1.022  -5.354  37.251
ATOM      2  CA  LYS A   2      -1.230  -4.312  38.301
ATOM      3  C   LYS A   2       0.011  -3.410  38.417
Example from RCSB PDB:
ATOM      1  N   ALA A   1      46.457  12.189  21.556  1.00 56.69           N  
ATOM      2  CA  ALA A   1      47.614  11.997  22.448  1.00 55.96           C  
ATOM      3  C   ALA A   1      47.538  12.947  23.645  1.00 55.17           C

I hope this helps,
