@BioinfoCopilot4 ай бұрын
Thank you very much! Autodock4 and Autodock vina serves equal purposes i.e. screening and docking. But the difference you might expect is that Autodock Vina is generally used to screen large number of compounds per se virtual screening whereas Autodock4 is mostly used for targeted docking where you exactly know the binding site. You can also use Autodock4 for simulated annealing and monte carlo.

of all the docking tutorials, I found this is very amazing and you help me a lot. Three questions. 1. while preparing the protein, should the missing atoms be not repaired? there is option for that in the edit-Misc-check for missing atoms and then repair 2. while trying to set map types for the ligand, F did not appeard by default and even when i tried to set docking parameters for the ligand, can i add it manually? 3. like the ligand's geometry is optimized, should't the protein be optimized as well? because the protein usually is found bounded with ligands or any molecules in the pdb and when this ligands or molecules are removed there might be a need to optimize the energy caused by the bounded ligands. Thank you
@BioinfoCopilotАй бұрын
Thank you very much! 1. Missing atoms should be repaired using another program called SwissPDB Viewer. Unfortunately, there are no options to repair missing atoms. 2. You can add it manually but before that you need to know the parameters. You might have to quantum mechanical calcutions to achieve that. 3. For docking no. But after docking you can subject it for MD simulation. 4. You can achieve all the properties during MD simulation. Remember docking is a static process and MD is dynamic.

@BioinfoCopilot Жыл бұрын
Yes, you can play around with the parameters as you wish. It depends what conformations you are looking for? Is it relevant with the experimental data? AutoDock provides several methods for doing the conformation search. Currently, the Lamarckian Genetic Algorithm provides the most efficient search for general applications, and in most cases will be the technique used. It is typically effective for systems with about 10 rotatable bonds in the ligand. The Genetic Algorithm may also be run without the local search, but this is typically less efficient than the Lamarckian GA-LS combination. Simulated Annealing is also less efficient that the Lamarckian Genetic Algorithm, but it can be useful in applications where search starting from a given point is desired. Local Search may be used to optimize a molecule in its local environment.

Hello! does anyone have an idea on how to dock a ligand that can not be downloaded from the internet. Let's say for instance, I made new compounds in the lab and I aim to dock them in the active site of a receptor I have downloaded from PDB, how do I do this? does this tool have any chemdraw feature that allows restructuring of ligands? I hope someone responds, this is very vital to my work, I'd really appreciate. Thanks.

Easy! Draw your chemical structure in chemdraw or chemsketch then save it as .sdf format. Open Avogadro, then optimize it and convert sdf to mol2. Then refer to my video and you can dock your ligands to the protein that you have downloaded. Follow my other videos as well how to convert sdf to pdbqt.

You are amazing indeed! Thank you so much for your help, it worked. I am a bit concerned though, i tried doing a 100 runs but it is taking too long, is there a shorter way? or what is the major difference between running 10 vs 100 because i have a lot of compounds to run.

Hello, I have an issue, after drawing my ligand with chemdraw and saving in sdf format then using avogadro to save in mol2 format, i have gone further to dock but at the end, the structure of my ligand changes by some bond rearrangement. how do i correct this please?

Hi Nerdalytics, please i'd really appreciate if you can be so kind to answer my questions. I seem to be stucked. Thanks a bunch for your help so far.

wanna ask something.. The reference rmsd and cluster rmsd, what are they exactly and which menas what? how do i interpret the results?
@busesahin55193 ай бұрын
isnt the reference rmsd values should be less than 2 angsgtrom?
@BioinfoCopilot3 ай бұрын
Cluster RMS is the root mean square difference in coordinates between this conformation and the cluster reference. Reference RMS is the rms difference between this structure and the input structure.
@BioinfoCopilot3 ай бұрын
If you have a reference ligand structure docked already (x-ray) then the position of the docked compound should be less than 2 Ang for best possible conformation

This is topological error. You have to correctly define your protein or ligand. Preprocessing is necessary.

Look in the C drive from where you executed Autodock or Autogrid

Check the log file (last couple of lines) and troubleshoot the error.

Might be the problem with the file path or autogrid path. If you are using windows always look in the C drive

I want to use AutoDock GPU, which accepts protein.maps.fld and ligand.pdbqt files. Since I am performing high throughput virtual screening, shall I just load protein and follow the above tutorial to create protein.maps.fld file, which I can use in my command line run of AutoDock GPU run? I have 1 million ligands in my screening library, so can't repeat the above procedure on all ligands, or shall I just pick a ligand that contains all types of atoms a ligand can have in that ligand library and produce protein.maps.fld based upon that ligand along with the given protein?

Yes, you can do it. I have used GPU version for 10000 ligands and it works. Here is the link: github.com/pritampanda15/AutodockGPU

You have to run the application from C drive only not from Desktop. You can run from Desktop as well if you set the path in MGL tools
