Splitting up a protein job using -runstyle gnuparallel

Hi, Im trying to run the simulations in parallel using GNU parrallel, the command I use is

./runI-TASSER.pl -pkgdir /home/sidney/Desktop/Bioinfo/I-TASSER5.1 -libdir /media/sidney/D804BAD104BAB23C/ITLIB -seqname A seq.fasta -datadir /home/sidney/Desktop/Bioinfo/Proteins/one/seq.fasta -runstyle gnuparallel -java_home /usr/ &

But it just throws up these errors at me for each of the simulations.

Illegal division by zero at /home/sidney/Desktop/Bioinfo/Proteins/one/PPAS_A line 354.

Has anybody had any success running I-TASSER with gnuparrallel.

Thanks,
