Hello,
I am working with a team that is trying to compare the fMRI data with the S3 facial action unit data and S4 emotion ratings data.
We’re finding that the facial action data has 1359 timepoints sampled at 0.5Hz/2 seconds, while the fMRI data and emotion ratings data contains 1364 timepoints (or the equivalent thereof for the emotion ratings data sampled at 1Hz).
Do you know where this difference in timepoints might be coming from?
Thanks a bunch for your assistance!
Sincerely,
John Andrew
