Heartbeats look bigger after removing ICA heartbeat components

,

Hi Marc,

Thanks for checking. For HH_30, IC37 (total 40 ICs) is the heartbeat IC, and for HH_31, IC14 and IC16 are heartbeats ICs (see below links for screenshots). I filtered the data from 0.3 - 150 Hz with notch filter 60 and 120 Hz.


I agreed that it seems like the weights and the inverse weights are mixed up. I used a similar pipelines before on different datasets with 60 participants and didn't have problems removing heartbeats (the same babies, different tasks, recorded in the same machine). The only differences were the filter done before ICA (3 - 55Hz instead of 0.3 - 150Hz) and the number of components I sent for ICA (25 vs. 40). I also have not updated the brainstorm codes since then so they should be using exactly the same codes.

Let me know what you think. I don't want to just switch to use SSP instead of ICA without knowing why ICA worked before on the same group of participants but doesn't work now.

Thanks!
