[modeller_usage] meaning of "env.io.atom_files_directory"

Hi everyone,

I am working on the tutorial in http://salilab.org/modeller/wiki/Missing%20residues. I have my pdb files in C:\Users\Sajeewa\Desktop\protease_project\modeller_practice directory. In the script to generate the model with all residues

# directories for input atom filesenv.io.atom_files_directory = ['.', '../atom_files']

should this be changed as

env.io.atom_files_directory = ['C:/Users/Sajeewa/Desktop/protease_project/modeller_practice'] ?

I don't understand what it means by

'.', '../atom_files'

Could you please explain?

Thank you
