Hi,

What could be the reason for this error (running on HPC):

Hi,

It might be you don't have write permission to the 227.158.Ku0p743e6_pol0p4_40ns_1500ns_temp223_strip1p3_Ku0p3_jan9227.out directory. Did you try deleting the directory before starting the simulation ? Could it be because the name is too long ? ( probably not but it's worth checking )

Thank you for your response.

  1. I am checking the long name
  2. It creates the .out file:

I don't know why, but, every time I am getting different errors, this is from the previous run (I am using mask):

Ok, I don't know why, but, shortening the name worked.

Also, it is good to hear from you Mathieu, I didn't recognize you without an avatar pic.
