Help1 Help! The problem with optofile

[firemars]

I cannot get any data when opreport
when I execute opreport I got the problems:

"opreport error : No sample file found: try running opcontrol --dump
or specify a session contraining sample files"

My operation procedure was
#opcontrol --verbose --start
I got:
