Dear Ms. Anna Ferrari,
Thank you so much Ms. Anna, I already found the ouput and plot the curve.
And what is the unit on the y axis of the curve, if I use photon part and dose-eq part in the USRBIN scoring? as I attach in this email.
Best Regards
M. Arif Efendi

Dear Mr. Arif Efendi,
first, please mantain the discussion public on the list... it is easier to
address the problems like that.
I ran your input, and I could correctly generate your USRBIN output file(s).
So, your input is correct... you should find in the directory where you run a
file prelimenary001_fort.21 (last time), or prelimenary001_fort.50 (now). This
is the file (one of the files if you send several runs) to be processed to
obtain the bnn file, but this you know.
...question: do you have enough space in your directory to write the output?
Regards,
Anna
