Calculate the average backbone Ca-C distances for PDB files.
Results included for the Top500 and Top8000 datasets of high resolution structures, and recent X-ray and CryoEM structures.
Run script with the following command:
python3 backbone_calc.py -n name_of_output_file -d directory_of_PDB_files -t threads
note: Include -i if you want to save all the Ca-C distances for a each PDB file.
