Trouble with drifting grating

Support
1

I’m trying to use the standard drifting grating stimulus to show static gratings that vary in orientation, spatial frequency, and contrast. When I run the program no grating is actually shown. I’m sure there’s something silly that I’m missing, but cannot for the life of me figure it out. The xml is attached.

Thank you,
Brittany

Hi Brittany,

You need to either

  1. Set the grating’s autoplay parameter to 1, or
  2. Explicitly start and stop the grating using Play Dynamic Stimulus and Stop Dynamic Stimulus.

That should fix it. If not, please let me know!

Oh my goodness, so simple! Thank you. If it doesn’t work I will let you
know. I’ll test it out when the rig is free.
