static_gratings stimulus

[alih100011]

Hello!

I want to extract the static gratings stimulus that show to the mouse by brain observatory cache. I have extracted natural scene stimulus by : data_set.get_stimulus_template('natural_scenes')

but I don't know it for static_gratings to attain its picture.

Thanks.

when I write :

   data_set.get_stimulus_template('static_gratings')

I see this Error :

KeyError Traceback (most recent call last)

in ----> 1 data_set.get_stimulus_template('static_gratings')

Can you include more of the script that caused the error? Specifically: which data release are you trying to access?

There is no stimulus template for the static gratings because the stimulus is generated programmatically, rather than consisting of images. There might be functions in allensdk.brain_observatory.stimulus_info to recreate the static gratings stimulus from the stimulus parameters.
