[AMBER] problem with parmchk and a big organic molecule

Hello,
I am trying to create parameters for a quite big organic molecule (212 atoms). I have used the Antechamber protocol to obtain the .top and .crd for smaller molecules many times, and everything was OK, but now I am receiving a Segment Violitation (Core) in the step of parmchk. I have used the option -l 9 in the steps respgen. This is what I done, the step where I get Segment Violation errors is the last one:


$AMBERHOME/exe/espgen -i lanzar_SP.sh.o4732912 -o cargas.esp

$AMBERHOME/exe/antechamber -i monomero_fullereno.mol2 -fi mol2 -o minimizado.ac -fo ac
$AMBERHOME/exe/respgen -i minimizado.ac -o minimizado.respin1 -f resp1 -l 9
$AMBERHOME/exe/respgen -i minimizado.ac -o minimizado.respin2 -f resp2 -l 9
$AMBERHOME/exe/resp -i minimizado.respin1 -o minimizado.respout1 -e cargas.esp -t qout_1 -O
$AMBERHOME/exe/resp -i minimizado.respin2 -o minimizado.respout2 -e cargas.esp -t qout_2 -q qout_1 -O
$AMBERHOME/exe/antechamber -i minimizado.ac -fi ac -o minimizado_resp.mol2 -fo mol2 -c rc -cf qout_2

$AMBERHOME/exe/antechamber -fi mol2 -i minimizado_resp.mol2 -c rc -cf qout_2 -fo ac -o minimizado_resp.ac
$AMBERHOME/exe/atomtype -i minimizado_resp.ac -o minimizado_resp_gaff.ac -p gaff
$AMBERHOME/exe/prepgen -i minimizado_resp_gaff.ac -o minimizado_resp_gaff.prepc -f car
$AMBERHOME/exe/parmchk -i minimizado_resp_gaff.prepc -o minimizado.frcmod -f prepc


Could you please help me to solve this problem? How could I get the .frcmod file for my 212 atoms- system?

Thanks a lot in advance.


Best wishes,

Rebeca.
