Hi @YvetteJxy, the problem was caused by your ligand PDBQT file, which doesn't have valid 3D coordinates but all 0s. You might want to review your procedure for ligand preparation.

If I guessed your ligand right and you generated it with obabel, here's how you could generate a PDBQT with coordinates and charges (although not necessary for vina) with obabel:

./obabel -:"C[S+](C)CCC(=O)[O-]" -o pdbqt --gen3d

REMARK    2  A    between atoms: S_2  and  C_3
REMARK    3  A    between atoms: S_2  and  C_4
REMARK    4  A    between atoms: C_4  and  C_5
REMARK    5  A    between atoms: C_5  and  C_6

Hi @YvetteJxy, Your upload appears as a HTML file (it looks very like the login page of Jupyter server). Let us know if you reshare the files.

One more thing about --autobox, in this scenario (a docking search), --autobox doesn't actually set the grid size or the grid center (?). --size_x --size_y --size_z are necessary even with --autobox, and if not specified the center seems to be 0,0,0. Not sure if this is related to the error.

Thank you for your help! I am very grateful for that!
I have uploaded the file again and I hope this time it will work!

@rwxayheee Thank you for your help! I think I know what the problem is! I didn't generate valid 3D coordinates of my ligand and now I have corrected my error! Thank you very much!
