Fix for simulation error? bzip2: Can't open input file rep*.tra: No such file or directory.

Hello,
I have been been unable to get your stand-alone program to work correctly. It appears from the output and error logs that everything runs fine until the simulation step. Each simulation run aborts immediately with the same error. I have read the other posts with the same error and checked seq.dat and exp.dat and they have the correct number of AA's (982). My cluster is running RHEL6, I have all the init.* files, and the cas_proteinsim command delivers and error at line 894 of file cas.f (Fortran runtime error: End of file). What else do you recommend?

Thanks,
Jerry
