I'm using ICA for artifact rejection and have questions about whether to keep or reject a few components.

(1) Is there a good how-to document for deciding which components to reject based on the features of the ICA (e.g., distribution of activity over the scalp, time, trials, power spectrum, etc.)?

(2) I have questions about 6 components (here's a link<https://www.dropbox.com/s/yikdd2fpfwx2ziu/forEEGLABlistserv.pdf> to a document with their graphs). Any thoughts about whether these components should be kept or rejected, and whym would be much appreciated!
