voxels that have no event #52

Closed Domi0222 closed 4 years ago

Domi0222 commented 4 years ago

When I applied rsHRF for my data, the event number of some voxels is 0. How are voxels without an event processed?

danielemarinazzo commented 4 years ago

It might happen, and in these cases of course no estimation is possible. You might want to check the signal for these voxels for anomalies though, since in z-scored "normal" BOLD data it should be possible to detect some events.

Hope this helps

Thanks for your reply. I’ m going to check my preprocess pipeline. Could you please tell me for my reference how do you normalize the data with z-scoring.

In matlab the command is zscore. It is already included in the code (it does not matter if you do it multiple times, provided you do it in the correct dimension).
