I went through your presentation sir and I was able to understand it. Thank you very much. We plead for more like this.
Ur welcome
Dear sir, nice presentation i want to do ligand ligand docking to find out hydrogen bonding possibilities in two different ligand to study interaction, how i can do this
This video will stand as a landmark in my future studies on docking. Well done and Thank you.
THIS IS SO HELPFUL! So clear! I have seen other ones which the youtuber makes mistakes and go back and forth, but with this one I really had the peace of mind and it worked in one try! Thanks so much for taking the time to make this! Already subscribed and will be going through other tutorials!
Thank you Prof! Well understood. This tutorial will assist me greatly in my in silico chapter.
I have saw various auto dock videos but your videos are so good and also discuss what would we facing issues during docking and you solved these issues during videos. thank you for giving CMD for docking. because i have facing python she'll error. Thank you very much Sir for making these videos. Most of people made the video but doesn't tell about issue but only your videos I saw which have discussed about also issues along with solve the problem. THANKS ❤️
hi i am facing python shell error please help me in rectifying it
Wonderfully curated Video Sir. From the start, till the endpoint I was able to keep up as exactly as you were demonstrating. Please continue to make such videos which makes our learning clear smooth and effective for future applications
Amazingly clear tutorial! Finally got autodock working!! Thank you so much!
Really good tutorial, not just what to do but also why. Thanks!
Thank you so much for tutorial. It was very useful for beginner and even non biology majors also understood clearly.
Glad it was helpful!
Wow!! Thanks a lot sir, I asked for this last time. It's a great to learn from the begining. Now I would like if you make MD simulation that will help me in my studies. Thanks in advance.
Thanks For Watching... Soon we will
Thank you sir for this, this is really helpful.
please keep posting more content like this.
Thank you, I will...
Many thanks for wonderful presentation.
A very helpful guide for a beginner like me. Thank you so much sir. I can understand a lot better after watching this video. I would love it if you can make a tutorial on how to do a controlled covalent docking using Autodock 4 as well
So nice of you.. sure i will look on it
Thank you very much. So helpful video
Really appreciate your efforts. May Allah bless you.
When I read a paper about andrographolide as a potential inhibitor of SARS-CoV-2 main protease: an in silico approach. The andrographolide compound has a free energy of -3.09 Kcal/mol, but it shows great binding when compared to other compounds having more negative free energy values. I think about pressure, temperature, and pH in the body affecting the inhibitory process
Indeed, this variable influences the inhibitory process; it is advisable to do molecular dynamics calculations to complete the molecular docking calculations.
Thank you so much for your video. Can I ask some questions: 1. Do I need to optimize the ligand before docking? 2. How to redock with co-crystal?
Very useful and easy to follow, Thank you
i love your video. this tutorial really helped thanks a lot, dear sir. can you do a tutorial on how to filter ligands during virtual screening campaign and how to validate a virtual screening protocol. thanks
u can check this video ua-cam.com/video/tFFxNTvvoJI/v-deo.html
Hello sir I am taking project on drugs design and chemistry but i have a lack knowledge what can i do for this.
Very much pleased wid ua vid sir...really really helpful....I have a query sir, while selecting autogrid and after launch it is not going to run....can u plz suggest me a solution ...thank u
what is the best docking tool for peptide interactions with protein or protein-protein interactions
Thank you for uploading such an excellent presentation.. Kindly if possible upload video about metal docking in ligand and how to prepare paramter file for metal. Thanks regards
Sure coming soon.. u can check my published articles.. u will find a tool for metal docking
Thank you for your kind response.. most of the bioinformatics and related field students wait for your tutorials.. please if possible kindly provide the link of the metal docking paper.
Thank you so much sir. Its a very helpful video😊
Good job! I really liked the tutorial. grateful.
Glad you enjoyed it!
I was able to successfully get up to time stamp @24:32. Upon trying to create the log file, something is going wrong. The log file will not generate in my parent folder. Not sure what is going wrong.
Edit 1) Thanks for including the autogrid workaround @33:25.
Edit 2) autogrid worked normally the second time I tried it through the regular program, I made sure there were no spaces or funny punctuation in any of the file names or folder names.
It is very very good! Thank you for work!!!
Very hlpful and thankyou sir! Can you please tell where to get the executable files (autogrid4 and autodock4)
Hi, hope it will help you - i found them occasionally after autodock installation in C:\Program Files (x86)\The Scripps Research Institute\Autodock\4.2.6
Hi, thank you for this great tutorial. It is very lucid and informative. Can you kindly make a video on docking of transition metal complexes as ligand and metallozymes as the receptor protein? It will be very helpful.
Thanks for Watching... Yes, soon

@SimranArora-hp5rq @plz send ur query to Dr’s email Address bbabajan@kau.edu.sa
Ok
Hello sir.. You have explained everything very clearly. It was very informative and easy to understand. I just wanted to ask the fourth amino acid which you selected was Lysine (270) and in the excel sheet it was given for Serine. Please clarify.
Yes, i saw that as well. I guess it was a mistake, he should have selected Ser272
Thank you for the video. How do you dock two proteins? Not protein and ligand
Very clear sir. Thank you
Thank you for the video
Ur most welcome
Hello sir, thank you for explaining so nicely. Kindly explain how to determine probable site of binding. I m working with bovine serum albumin and am finding it difficult to identify site I and site II. Please help me. Thank you.
When pasting into OpenBable GUI, make sure that the input format is selected as sdf - - MDL MOl format. My ligand file would not convert to .pdbqt until I made this change.
Open Banel GUI having multiple options ... check input file format correctly
Thankyou..it was very helpful
Hi. Many thank for your great description. but i couldnt find autogrid4.exe file. could you help me?
I am very happy to understand all these very clearly but there is a problem facing when I am doing docking of my derivative plz you can help me
finally i got my output with your tutorial, thank you sir... but i haven't get any rmd table in dlg file and i have get no more hydrogen bonds are created in analyzing conformations, may i know the reason sir and please tell me how to rectify it
Wow, really insightful
Sir, thanks for such an informative video! I just want to ask if our ligand is away form the protein or receptor then what should we do?
Same question. Does the program automatically place the ligand in the binding pocket once it is loaded?
Hello Sir, in Openbabel I selected the sdf - - MDL MOL format to upload my 2D ligand but in output the pdbqt format is not displayed. There is just pdb format. My ligand is simply a cadmium ion and the protein is IVQQ present in Streptococcus pneumoniae. If I convert sdf to pdb format the ligand file is not getting opened in Autodock. To which format should I convert the ligand sir? Thank you
If I go to run autodock it starts and shows the little window for just a second and then nothing heppens anymore… No files are created but there is also no error showing up… What can I do?
Hi
thank you very much for your video.
I'm trying to dock but I can't do it because I get an error that says: Sorry, I can't find or open Grid Parameter File. I checked your video and I have everything the same, I don't know what the cause of the problem would be. I created a folder in documents which contains the files and also the executables for autodock4 and autogrid4; executables that were initially found in a folder called: The Scripps Research Institute located at C: \ Program Files (x86). I have tried to do several maneuvers but I cannot start the program. Thank you, if it is the case, help me with this difficulty.
share ur error screenshot in our Bionforamtics facebook group
Plz make detailed video on protein Ligand result analysis as soon as possible.. I need this in my final year research project.
Thanks For Watching... Soon we will
Hi, Brother Thank you for wonderful video. Please make a video, "How to add atoms in autodock parameter file". Because most of the metals are missing in autodock parameter file. For e.g I am facing a problem in preparing receptor file for pdb Id 1E9Z which contains Nickel items.
When i add kollman charges, no charge were added to the nickel. Please let me know how to handle with the metals which are not available in parameter file of Autodock
Hello sir, how should we get the executive files like autogrid 4. If anyone knows about that please explain
Hi thank you for good video ! I want to ask, what if we put xyz randomly as long as the ligan in the cube ?
Cool video! Is fortran, c++, or python used to predict binding affinity and to what degree?
very informative ty sir
Ur welcome...
sir when i want to save the GPF then i get error and shows that you must select macromolecule before writing gpf
Sir , what if the ligand is not inserted to the protein
Hello,
Autodock reported some residues are missing atom. Actually I could see a non-bounded atom near residue. Guess need to add a chemical bond in between. What should to do next?

Hi great tutorial. I have a question. I typically use a config file but it doesn't contain any information about the GA parameters, so I take it I'm using default patameters? Can I put this information into the config file or can I put it in as a flag into the command lìne?

How can you validate your docking method in Autodock / Autodock Vina. Normally, we perform docking process with co-cristalized ligand of crystal structure and calculate RMSD value. If it is less than 2A we can accept that our docking method is good. In autodock we get different rmsd values, reference rmsd and cluster rmsd etc. In publications how'll we state the validation of our model?
What I do if I have 2 chains for my protein
I wonder if the best conformation is the one with the highest affinity or the one with more hydrogen bonding as explained by others like
Dr. RAVIKUMAR CHANDRASEKARAN and it could have a lower affinity. would you explain, please
why did I miss the file it can't be created, I don't know where the mistakes will be glg file is missed what do I have to do?

How can I download Autodock tool, Open Babel and VMD in one folder?
Hi, thank you for this well explained tutorial. I am facing this while ligand preparation- every time I try adding the ligand it shows an error that ligand.pdbqt cannot be read. Also, when checked, open babel shows a message that '0 molecules converted'. Tried numerous things but none worked out. Can I get any help on this?

can you pls help any metal ion related docking
from where these application "autodoc4 , autogrid4" we will get ? i mean inside MGL Tools i can not see anything named it. could you please help what exactly i need to have in the working directory.
Small doubt @13:20. In this tutorial you have added only "polar hydrogens" to the protein structure, but in autodock tutorial it is mentioned to add "all Hydrogen" - So whatis teh difference bewteen these 2 ? How adding all Hydrogens or polar only hydrogen affect the docking result ?
try running an experiment comparing the results when the two different options are used and see what happens. Perhaps this relates to giving preference to hydrogen bonding over a balanced consideration with hydrophobic interactions included. I'd be willing to bet incorrect results will occur if only polar hydrogens are used in the simulation when hydrophobic interactions are important for binding.
lets say i have one receptor/ and about 20 ligands, i am supposed to do this for each ligand? or one is enough
Can you please do a tutorial on Codon Analysis by using CodonW?
sir if a person gets a large positive value with my protein somewhere around 2856kcal/mol. In autodock vina i received a normal binding energy of -10.1 kcal/mol with the same target and ligand. What could have gone wrong according to you?
ur question is not clear to me. if ur talking about protein-protein docking, yes u will get highest docking energy values, b'c there are many residues are involved in interaction for that reason u will get many h-bonds, vdw, ioinic interaction etc., but when it's come to small molecule u will find very minimal interactions.
With vina and Autodock, i m getting very different results.
mentioned autogrid4 and autodoc4 downloading links are not working. Can you please mention a working link so that I can download those
