Ouch. I made those videos seven years ago.. Hope the video helps, but now I'm embarrassed.

You can enter there the PDB ID of your molecule or upload a PDB file. It should generate force field and input files for you.

I should be highly thankful to you if you suggest me how to start for this. It look silly to you but I searched the website but unable to find the download and tutorials. I am new to CHARMM but I understand it is important to learn.
