[Eeglablist] Study clustering on a specific frequency band

[Makoto Miyakoshi]

Dear Maya,

subject's data on that specific frequency band before creating the study
and then to run clustering on that data?

That works.

> or Is there a way to run clustering on a specific frequency band setting
the preclustering frequency parameters to the frequency band of interest?

You can specify frequency range in ERSP when clustering. It should be
easier for you.

However... does ICA identify gamma? I doubt it. This is because 1) gamma
has small amplitude 2) gamma does not have a broad network. When I found
gamma, it was almost always coupled with theta (and it could have been just
micro tremor of eyes...)
