Hello Modeller Users,

I am building models in the way described in the basic tutorial. I noticed that the completed model PDB is missing the chain ID column. The template I am modelling from has only one chain, A. Here's an example:
Template:

ATOM      1 N   SER A   2      -6.487   9.533 21.436 1.00 2.23       1SG   2
ATOM      2 CA SER A   2      -5.822 10.328 20.343 1.00 2.86       1SG   3
ATOM      3 CB SER A   2      - 6.345 11.788 20.283 1.00 2.67       1SG   4

and model:

ATOM      1 N   SER     1      -0.662 11.979 19.810 1.00 65.26       1SG   2
ATOM      2 CA SER     1       0.191 12.970 19.122 1.00 65.26       1SG   3
ATOM      3 CB SER     1      -0.325 14.388 19.420 1.00 65.26       1SG   4

Is there a way to force Modeller to print the chain ID? I convert the resulting PDB to charmm format, and some unpleasantness follows because of the missing chain info.

Thanks for your help!
