I-TASSER problems with parallel version

I am running I-TASSER 3.
The sequential version is running ok. It has been running for several days now.
I am having problems running the parallel version. I did modify the script runI-TASSER.pl to run in SGE.
(Only the parameters sent to SGE)
I am getting the following error:
Routine ==> err_dPPAS2_test8
Illegal division by zero at dPPAS2_test8 line 355.
I guess is not finding the file rst.dat.
When I search for this file I found:
dPPAS2_test8:open(out,"rst.dat");
dPPAS_test8:open(out,"rst.dat");
Env-PPAS_test8:open(out,"rst.dat");
MUSTER_test8:open(out,"rst.dat");
PPAS_test8:open(out,"rst.dat");
wdPPAS_test8: `$java_exe/bin/java -Xms2512m -Xmx2512m -jar fGGGd.jar > rst.dat`;
wdPPAS_test8:open(out,"rst.dat");
wdPPAS_test8~: `$java_exe/bin/java -Xms2512m -Xmx2512m -jar fGGGd.jar > rst.dat`;
wdPPAS_test8~:open(out,"rst.dat");
wMUSTER_test8: `$java_exe/bin/java -Xms2512m -Xmx2512m -jar fQQQ.jar > rst.dat`;
wMUSTER_test8:open(out,"rst.dat");
wPPAS_test8: `$java_exe/bin/java -Xms2512m -Xmx2512m -jar fNNNd.jar > rst.dat`;
wPPAS_test8:open(out,"rst.dat");

It looks like the file rst.dat was not generated. However, in the serial version I do not get the error.
Any advice will be welcome.
Thanks,
Octavio
