The first lines represent the command that I run. I can notice two errors in the output:
1. At line 522 of file zal33.f
Fortran runtime error: End of file
Illegal division by zero at ~/I-TASSER/I-TASSER4.1/tests/ab28wt/MUSTER_ab28wt line 599.

2. At line 1714 of file cas.f
Fortran runtime error: End of file
bzip2: Can't open input file rep*.tra: No such file or directory.

Does anybody have a solution for this? I saw posts with similar errors, but the solutions given there did not seem to apply to my current case (I tried them, but could not find the steps coherent to my set up).

Good day.
