This is the error i countered when splitting a mol2 file containing 651 ligands
raccoon stopped when the mol2 folder contain 648 ligands and the pdbqt contain 26
please advise
many thanks

Hi,

it seems there is a problem with the structure file of the ligand ZINC06494597.
Try to visually inspect it and if the structure looks correct, remove and add again the hydrogens to it.
Unless you deleted the files generated, you could simply try to import the splitted Mol2 generated by Raccoon (including the fixed ligand), instead of repeating the entire splitting procedure from the beginning.

Hope it helps,

Stefano
