[PyMOL] Script for iterated `align`ment

[DimitryASuplatov]

Hello,
I have 21 pdb files in my folder. I wrote a small script to load them
all at once to the Pymol

**********************************************
import os
import re
from os.path import join, getsize

p = re.compile('[A-Za-z\.]*pdb')
w = re.compile('nowater')
for root, dirs, files in os.walk('./'):
    for file in files:
        if p.search(file) and w.search(file):
            cmd.load(file)
**********************************************

Now I see them in the viewer window.
I want to align 20 of them to the remaining one structure and to be able
to store the RMSD in external file.
Could this be done automatically?
I am asking because I typed `help align` and found no API for it.

Thanks for your help.
