[Eeglablist] PCA preclustering

[Makoto Miyakoshi]

Dear Shiri,

Sorry for slow response. The warning message means that if you separate the
within-subject conditions into different set files, they should share the
identical ICA weight matrix. This also means that ICA should be run on the
condition-unseparated data, and you should not run ICA on different
within-subject conditions. Please check if it holds in your case.
