Hi,

I want to generate pdb files for every 100 frames of a simulation.
I have the .xtc file for the simulation, but to my knowledge, this only
contains coordinates and not enough information to generate a pdb.

When I tried to "save coordinates" as a pdb in VMD, I got an error:
Molecule's structure has not been intialized.

 I'm guessing that I can load some other file with information about the
element of each atom, etc?

Any help would be appreciated.

Thanks,
Matt
