Dr. Dweipayan Goswami! Thank you for this video! I couldn't find an error in my docking. After your video - I did it well! 1000 thanks and I wish you all the best!
Good explanation. I have used Combination of UCSF chimera and Pyrx for docking. Pyrx used same algorithm as autodock Vina. Only advantage I got in pyrx was it is much faster because it loads and minimised multiple Ligand in much lesser time than chimera where we individually add every ligand and save it.

wonderful explanation using UCF Chimera. I am unable to install UCF Chimera on Linux subsystem on Windows 10. May we do docking in windows and Pymol or in Linux using PyMol. Kindly tell if possible. Still I really appreciate your lecture. Thanks May God bless you.
The Pose1.pdb file is not prefixing the lines for the atoms of the ligand with "HETATM" They are all prefixed with ATOM. That might be why if I am just putting the poae1.pdb file into PyMol, it is only rendering the protein and is not "seeing" the ligand.... actaully I just had to select "All States" in Pymol
There shouldn't be an issue .. i cannot say without seeing an error ... Just repeat the exact same steps with another ligand .... Or after minimizing ligand go to Files > Save .mol2
Hi Dr. Dweipayan Goswami, While performing docking using VINA library in chimera, It throws an error saying "too many heavy atoms (>100) in ligand chimera docking". Does chimera offer VINA docking only for very small molecules (atoms < 100) or I am doing something wrong? How to get it done? Thanks
Sir, I am getting an error "Too many heavy atoms (>100) in ligand"? I am Docking receptor as protein and hormone as ligand both files were taken from PDB in .pdb format is ok?
@@DweipayanG Sir, this is my second attempt to perform docking by watching your lecture series. last time was done successfully, this time I think both are kind of protein which cz the error.
Hi Good video, but I have a question. When you save the pose 1 you merge the naked_protein and the pose with the best affinity, but you have done the docking with the prepared_protein.mol2, so wouldn't be more correct to save the pose 1 with the protein_prepared and the ligand insted of the naked_protein? Because well, you performed the calculations with the prepared structure Thanks and I hope I have explained to you correctly
Mol 2 files changes the numbers of amino acids of the protein which creates problem in understanding protein ligand interaction... Hence when u save the pose use the naked protein file which is in pdb format so all elements of files are not altered .
@@DweipayanG But, for example I've I saved the protein_prepared in pdb instead of mol2, the step in the MD simulation where I prepared the protein wouldn't be necessary, or I am wrong??

Amazing tutorial
Evrything went perfect until the (7:00)sudo command, it says it wasnt recognised as an internal or external command or batch file. How to fix that?
THANK YOU!!! This is so clearly explained.

Install exactly the softwares as i have shown in video …. As far as i can see installation properly will resolve this issue
And it will not work in windows , use Linux

Sir, can you explain how to run hole2 programme for protein pore calculation
Does the resolution for the protein or receptor need to be low? If your answer is "yes", can I know why?
veryyyy useful
Vai awesome
How to do check the superimposed between original legad and and docked legand and it's impossible to to superimposed between Other
Its possible in ucsf chimera and i have shown that in my videos too how to do that …
@@DweipayanG
If that occur that means the docked ligand and co-crystalized ligand are same ??
@@DweipayanG
I see your co cryslazed ligand and docked ligand are same ?
Please explain sir
respected sir, plz make video on docking by autodock tool
32.10 min. I am not able to creat mol2 file. I am following all the steps u mentioned ...still i am not able to creat....what could be the reason
There shouldn't be an issue .. i cannot say without seeing an error ... Just repeat the exact same steps with another ligand .... Or after minimizing ligand go to Files > Save .mol2

Ligand file has to be a .mol2 file
@@DweipayanG Sir, alreday did as per your guidelines but at the end i got the error.
@@DweipayanG i got two files protein.mol2 and ligand.mol2 both were run through chimera- autodockvina after "apply" key get error prompt
In the last step i guess u have chosen protein as ligand and ligand as receptor in the top part of vinna panel !
