Missing gaze data for some sessions

I’ve been using the AllenSDK Visual Coding dataset for a while now and it’s been working great.

Recently, I’ve been looking to augment my analyses using eye-tracking data, but found it doesn’t seem to be available for the sessions I’ve been using.

Here’s the error I’m getting:

This ecephys session ‘732592105’ has no eye tracking data. (NWB error: “‘eye_tracking’ not found in processing of NWBFile ‘root’.”)

Specifically, is the data just missing/not recorded for some sessions, or am I doing something wrong (here with the session.get_pupil_data() method).

Any help would be much appreciated!

Hi @sebbkw – you’re accessing the data the right way, but unfortunately the eye tracking data is not available for a subset of sessions.
