Hi everyone, I am interested in running an ICA decomposition on a 128-channel set of epoched EEG data, specifying the number of components I would like the solution to include (I can run the decomposition successfully to produce 128 components - I would like to request fewer). Using the pop_runica GUI, I have attempted to use the ncomps option (and have reattempted to use ncomps using every modification of the syntax I could think of) but receive a variety of errors. I'm wondering if anyone has any experience using the ncomps option for runica, and if so, could you suggest specific syntax. Or if anyone has any suggestions as to how I could approach the problems differently, I'd sincerely appreciate the input. Thanks in advance for your time, Peter ---------------------------------- Peter Bachman PhD Candidate, Clinical Psychology UCLA Department of Psychology
