[Moved from CFDEM(R)workbench forum] LPP showing wrong chuck size

Hi,

I am very less knowledge of LIGGGHTS software. Actually after running a test case I tried to create vtk files using lpp tool which I installed from github. But after giving the command in terminal
lpp dumb.filename
it shows the message invalid or wrong chunk size. I set the chunk size 8 on lpp.py file. BUt still it shows the same.
Can you give me any suggection?
