I am trying to do molecular docking of protein and a drug molecule. but the dock.glp file is showing the below error. the molecule(ligand) name is molecule 1.pdbqt but it is showing that can't find or open "molecule". pls help !!!

Coordinates of Central Grid Point of Maps = (-14.010, -43.830, 27.660)

Macromolecule file used to create Grid Maps = Processed_AChE.pdbqt

Grid Parameter file used to create Grid Maps = C:/Users/kashy/Downloads/Docking/grid.gpf

Minimum coordinates in grid = (-21.510, -51.330, 20.160)

Maximum coordinates in grid = (-6.510, -36.330, 35.160)

DPF> map Processed_AChE.A.map # atom-specific affinity map
