My name is Cathy. I'm a new user of Modeller, and I'm still trying to figure out the input files to run Modeller. I'm having trouble with the atom files...I don't exactly know what is an atom file.

I tried using the .pdb file straight from the PDB. I tried changing the file content to just the "atom" section of the PDB files. And nothing seems to work.

I have the script file & alignment file in the default Modeller directory, and I set the atom file environment to a folder named "atom_files" with the 2 atom files (1pme & 1wbn). But when I try running my script, it says that atom files cannot be found in the directory atom_files. Here's the exact error message:
