Dear Sadaf Rani,
Try creating residue units in memory (variables) with the same name as the residues that you will intend to use later in the PDB file:
NAP = loadmol2 NAP_amber.mol2
BG6 = loadmol2 BG6_amber.mol2
If you then execute the command "list" you should see "NAP" and "BG6" among other available units in the library.
Leap uses that library to assign types and topologies (connectivity) to molecules in the PDB, which lack that information.
Best,
Matias Machado

Asunto: Re: [AMBER] tleap ERROR
this line in your tleap input file probably is the reason.
Shouldn't it be ligB for BG6_amber.mol2 file?
ligA = loadmol2 BG6_amber.mol2
