hello, i find molecular dynamics hard to learn as i had no prior experience with coding and linux (what my teacher recommended me to use), videos like this makes it very easy for me to understand the concept and how to do it. THANK YOU FOR THE VIDEO!
Great tutirial and very informative one. Kindly if possible add ligand and DNA docking tutotrial. Sir it would be great job on your part. Thanks regards
At 17:55, Spacing parameter is set 0.375 A, but this is not used by AutoDock VINA. Changing this parameter affects the grid box size. So even you attempt to perform site specific docking, the docking is going to be blind docking due to this parameter. I am not able to get the clarification about this parameter while docking except VINA official tutorial has this option set as 1.
@@saikatmandal929 I understood that you don't have to use vina.exe but directly autogrid4 and autodock 4 on autpdock tool. But when I try to put the new parameters the program doesn't run
I'm in bsc 2nd year and I could understand anything sir ... I'm just curious why did you remove the water molecules and add polar hydrogen to the protein ??
Sir, at 9:25 you add Kollman charges to the protein. However, at 15:23, when you load the protein macromolecule, you click on 'no' for preserving Kollman charges. The next popup box states that Gasteiger charges were added. So, should we add Gasteiger charges for the protein?
I have a doubt. I guess The grid box has to be formed around the active site residues by changing the x, y and z axis values so that the interaction can be calculated correctly,
Thank you Sanket Bapat. Both the videos are very neatly and clearly presented. Highly informative. But once after docking how are we to interpret it in the paper. Any suggestions or advice regarding the same.
Thank you sir for such a nice video. One question- if we don't know the active site, why we are not enclosing the whole protein inside the grid by changing dimensions.?
As we all know that docking simply interaction between receptor and ligand molecule, before docking we do remove the water molecule and some other additional ligands molecule , and add polar hydrogen bond also, Afer that we dock between receptor and ligand molecules, and more negative sign give the good stability.....but sir my question is that in natural condition how water and additional ligands remove from receptor molecules and how will i add polar hydrogen also?
Great job dear Prof. highly appreciated. I am quite new to molecular docking and trying to perform docking of activated carbon and a drug using your video as a guide. Will it be possible?
Hi very informative tutorial on AutoDock Vina but I have a question which is that what about if we don't know about the ligand binding site of our protein so how can we set the grid?
Good day to you sir. Thank you for this excellent interactive session. I have a query, What is to be done if ligand profiles are not seen in the downloaded material from PDB.
Im performing docking on a known active site so i limited the gridbox around the active site only. Some of the conformations i got after docking were outside the grid box. Is that normal?
Hi thanks for this, came at the right time! When adding the grid box, is it generated automatically at the binding pocket or will have to adjust it? if so, how do i ensure its the 'correct' coordinates?
Could you make a video showing how to dock in Vina Auto-docking using some flexible active site waste? I need my molecule to interact with specific residues and I don't know how to do it. Please.
Hi joyce I think you cover all the protein by doin grid box so it will be flexible as you took all protein whereever will get less energy it will enter
Hi Dr. Sanket. I am an IBDP 2 student. For my school project I need to conduct multiple ligand simultaneous docking. I was able to conduct single ligand docking but am unable to understand how to do MLSD. Can you please help with instructions on how to do this. Thank you
If I use a receptor that I have already known the binding site with a reference ligand, how can I set the grid box in that binding site only for docking with other molecules?
Should we follow the default grid box dimensions mentioned in the autodock vina ? Wouldn't it be correct if we first checked literature for the docking site and then changed the dimensions of the grid box? Dr. Sanket , could you clarify this ?
Hi! Thank you very much. i learned a lot from your tutorial. May I ask, how can I specify the number of docking runs in Autodock Vina? Is it possible? Coz I am planning to dock at 70 runs.
Hi! very helpful video indeed. I have one query which is my SDF file is not getting recognized as a SQLCE database. how do i overcome this error? Kindly help..
Hello sir, when i click on grid and selecting the protein then get error, showing protein pdbqt has one or more hydrogens with no bonds. Plz solve this problem
Hey very nice and clear presentation. Wanted to ask one question so the final poses that you visualise in pymol and if we suppose find the first pose as the best docking pose how do we save it and use for showing it in power point?
Thank you so much for your video Dr. Sanket. Firstly I hope you are healthy and safe. I'm trying to perform a molecular docking but I have an error while trying to save the PDBQT file: Unable to assign HAD type to atom Mg Unable to assign valence to atom protein:B: MG2003:MG type = Mg Unable to assign HAD type to atom Mg Unable to assign valence to atom protein:D: MG2003:MG type = Mg By any chance, do you know how to solve it? Thank you so much in advance!
i use pyrx for docking, and use multiple ligands i download them from zinc database (nubben database for natural compounds), i do minimization and docking but when finish the result are encodede for the compound it just codded the energy , and they are 2332 compound how can i know the compound crosspend to each result???
Thanks for such a nicely presented video, especially for beginners. However, during the protein and ligand preparations, i am unable to save file in pdbqt format. kindly guide through some tips, which could work for me
can anyone please explain my following question? this particular protein "4mzi" in this video has some missing residues in its side chain. so is it possible to do docking without fixing it ? in this mgl tool he didnt fix the missing residue. will that make good docking ?
Sir.. Everything is useful in this video. But am unable to download PyMOL. My system can't allow that to instal. So, kindly send the ligand format file, sir.
Respected sir need help The command shows the program is not recognized as an internal or external command operable program or batch file what is the solution for this problem
hii.. I need your help. everytime I am trying to save as pdbqt format, my file is being saved as pdf.. could you please tell how to resolve this problem
Hello Sir! thank you for your videos,i have a question ,when i drug the pdb files into Autodocktools software,it occurs a error “4mzi.pdb does not exists”,hope you can help me to solve this problem,thank you!
