Hi,
Thanks for the suggestion. Can I clarify it? How am i supposed to "use computational modeling to get the PDB file of the deleted protein"? What sort of simulation would that be? I was planning to, in the pdb file, delete the lines corresponding to the amino acids. Then what?
Thank you,
Sonya

My way to do that is to use computational modeling to
get the PDB file of the deleted protein, then run
sander.
Best regards.
