I usedthis command;
antechamber -i threonine.pdb -fi pdb -o threonine.mol2 -fo mol2 -c bcc -s 2

these are my files;

threonine.mol2
ANTECHAMBER_AC.AC0 ANTECHAMBER_BOND_TYPE.AC sqm.pdb threonine.pdb
ANTECHAMBER_AM1BCC.AC ANTECHAMBER_BOND_TYPE.AC sqm.in


then i use this command;
parmchk -i threonine.mol2 -f mol2 -o threonine.frcmod

but the threonine.frcmod file is empty;

remark goes here
MASS

BOND

ANGLE

DIHE

IMPROPER

NONBON
