Respected Sir

1. Can I get any detailed documentation explaining mutate_model python script.

Since, I am a beginner both in Python and MD Simulations, I am finding it tricky to understand this script.. The link is as follows.

2. My second doubt is " How and where can I specify the mutation. Is 1699 mentioned in this script "RESIDUE POSITION " and LEU as "MUTANT RESIDUE" ?

3. My third doubt is how much time will it take for this script to run  ?

4. My Fourth doubt is at the end, will I get single or multiple models ? If the output is multiple model, how shall I select the best one ?

Please send some detailed documentation for this script. I am unable to understand the basic logic behind this script..

I will be highly obliged.
