ICA Components selection

Hello,

I’ll like to inquire the implication of selecting “unnecessary” components after running ICA on my dataset. This is because I utilized ICA for artifacts removal in my dataset. Now, I got 28 components in all and I really don’t know want can be used to guide my components selection.

Also, how do you select the optimal components for ICA artifact removal?. Is it subjective in its selection?

A figure showing an exposition to the question is provided below:

We cannot guide you precisely with these questions, as we are not experts in ICA labeling or selection.
But google can guide you in a rich EEG/ICA literature, especially in the EEGLAB community.

Example: SCCN: Independent Component Labeling

Thank you for providing the link and for your response.
