*MATRIX GENERATE - Global Stiffness matrix

Thank you  for your reply. I know but I was wondering if it is possible to omit them manually.

 One more question, I figured that using *MATRIX GENERATE, one could get the global stiffness, mass or load matrix in a ".mtx" file. But I am wondering why I can't get the file after the run.
