The error while running tutorials

Dear all

I have downloaded and installed OF and Ligghts. I did everyting following the guideline. it seems that the compilation works out, but the turotials can not be run properly.

First, when I try "cfdemTestTUT" and get error as

"cannot remove `cfdemSolverPiso_settlingTestMPI.eps'"

Then I go to the CFD forlder and put "mpirun -np 2 cfdemSolverPiso -parallel"

and get the following errors:

It seems to me that "cfdemSolverPiso" is there, so the compilation is fine (am I right?)
But the initiation of particles has never been in effect. Actaully I try to run all examples seperately, and always got the similar error indicating that the initial particle information is missed.

Onething confusing me is that, in the guideline it indicates "To specify the paths of pizza, please check the settings in $CFDEM_SRC_DIR/etc/bashrc", but I can not find pizza in the path. I try to download it, but it seems the download is no more available. I am not sure if that is the reason why I can not run the case.

Best regards
