Hi,

I would like to get whether an animal was rewarded or not per image presentation from the SDK datasets but cannot find it. There is a ‘insertsession’.rewards file but it’s of length 70 instead of ~4400 or the number of image presentations.

Thanks!  
Tristan

Hi Tristan,

The `rewards` dataframe contains the timestamps of each reward that occurred during the session. To associate the rewards with each image presentation, you have to do a little bit of translation between the two dataframes to find the reward times that fall between each image presentation start and end time.

I’ve made an example jupyter notebook [here](https://gist.github.com/matchings/846e7633d57501b5af55f4daae22a4d9) that shows how to do this.
