hello,

I'm trying to do molecular docking using pymol and autodock 4.2.

I'm just learning how to use autodock now, using instructions online and youtube and it's quite difficult.

I was trying to follow the instructions in this video ( https://www.youtube.com/watch?v=blxSn3Lhdec&t=630s ), but at some point I had an error and didn't understand how to continue, so I could use some help.

after saving my molecule (protein, not the ligand) and marking all the binding residues I was defined a grid box and fit all the residues within the box. after I defined the grid box I was to save the grid box in a file and press file- >output grid dimensions file. after I clicked the latter a warning appeared.

"AD41gpf_setGrid WARNING

Please specify a receptor before trying to write a grid dimesions file"

Again, I'm only becoming familiar with autodock and the hole process so I'm not really sure what I'm doing yet, and just trying to follow the instructions in order to do it right.

I would appreciate any help.

Thank you very much,

Sapir
