This part is a continuous toturial following the virtual screening of choosed system ([http://ringo.ams.stonybrook.edu/index.php/2020_DOCK_tutorial_4_with_PDBID_6UZW]). All the files generated in Virtual Screen session are share with De novo session.

This tutorial assumes that you have finished the virtual screening of this system ([https://ringo.ams.stonybrook.edu/index.php/2020_DOCK_tutorial_3_with_PDBID_4F4P]). We are going to used some of the files generated by the VS toturial.
+
In this part, we will generate the same ligand present in the structure by connecting  fragment from scratch. By putting the generated "ligand" back into the pocket, one could check how our simulation works in terms of the protein they interested in.

Once fragment generation is completed, six files will be generated. (fraglib_linker.mol2, fraglib_rigid.mol2, fraglib_scaffold.mol2, fraglib_sidechain.mol2, fraglib_torenv.dat, fragment.out_scored.mol2)

By type the following command or open the mol2 file in Chimera, one can check the number of fragments generated and see how they match with the original structure file.  
−
You can use the following commands to check the number of fragments in each file.
 
  
 
  grep -wc MOLECULE *.mol2
 
  grep -wc MOLECULE *.mol2

−
You can also open the mol2 files using chimera and check if the fragments match with the ligand used for fragment generation.

The generated fragments will be used to perform the de novo dock. Here the fragments will added together restricted by different properties like maximum layers, formal charge and molecular weight. Before each connection, DOCK will check with the torsion environment file created in frgment generation to see if that particular connection is seen before. If not the connection won't be made.
+
We will run de novo dock using fragments generated before. The fragments will connected with each other one by one with constrains such as charge and molecular weight. DOCK program will make sure the connection is reasonable before adding any single fragment.

You will now have a file in your directory called descriptor.output_scored.mol2 which can be loaded into Chimera using ViewDock with your original ligand .mol2 file.
+
You will have 5 files generated in this file when the process is completed. Open a file named descriptor.output_scored.mol2 in Chimera with the function "ViewDock", one can compare it with original ligand .mol2 file.

This part is a continuous toturial following the virtual screening of choosed system ([1]). All the files generated in Virtual Screen session are share with De novo session.

I. Focused De Novo Design

In this part, we will generate the same ligand present in the structure by connecting fragment from scratch. By putting the generated "ligand" back into the pocket, one could check how our simulation works in terms of the protein they interested in.

Fragment Librarie

A focused fragment library will be generate, based on original ligand molecule, in order to building the same ligand in a atomic structure.

Create a new directory for the fragment library. 

mkdir 10_dn_fraglib

Create a new input file for fragment generation. 

touch fragment.in

Complete the input file by answering default questions from dock and run it by calling the input file through DOCK6

Once fragment generation is completed, six files will be generated. (fraglib_linker.mol2, fraglib_rigid.mol2, fraglib_scaffold.mol2, fraglib_sidechain.mol2, fraglib_torenv.dat, fragment.out_scored.mol2)

By type the following command or open the mol2 file in Chimera, one can check the number of fragments generated and see how they match with the original structure file. 

grep -wc MOLECULE *.mol2


Focused Denovo Growth

We will run de novo dock using fragments generated before. The fragments will connected with each other one by one with constrains such as charge and molecular weight. DOCK program will make sure the connection is reasonable before adding any single fragment.

Create a new directory for focused denovo dock. 

mkdir 11_dn_focus

Create a new input file. 

touch dn_focus.in

Complete the input file by answering default questions from dock and run it by calling the input file through DOCK6 

dock6 -i dn_focus.in -o dn_focus.out

Generic Denovo Rescore

Create a new directory 

mkdir 14_dn_generic_rescore

Create an input file 

touch rescore.in

Complete the input file by answering default questions from dock and run it by calling the input file through DOCK6 

dock6 -i rescore.in -o rescore.out
