Dear all,
I am trying to use component clustering tool in the eeglab.
I have divided each subject's data into 500ms epochs. For 5 subjects I got 25 epochs and consider each of them as an individual subject for analysis purpose. Then created a study using 25 epochs. When I use 'Build Pre-clustering array', it is creating a parent cluster with only 150 ICs (5X30) instead of 750 ICs (25x30).
I have computed ICA weights before dividing the each subject's data into individual epochs.
I am not sure what is the reason behind this.
Thank you for your time and help.
Kind Regards,
Naga
