2018 Denovo design tutorial 1 with PDB 2NNQ

Files Needed

Fragment Libraries

A focused fragment library will be used in this tutorial, in order to attempt building the same ligand. A focused fragment library can be generated using the same ligand.

Create a new directory for the fragment library.

mkdir fraglib

Inside the fraglib directory create a new input file for fragment generation.

touch fraglib.in

Generate the fragments by calling the input file through DOCK6

dock6 -i fraglib.in
