Martin,
Thanks for the info. I'm not entirely sure converting to an image is what
I really want to be doing. I am using SPM's EEG processing capabilities
as the pre-processor for a custom module I have written to perform other
types of EEG analysis. What I need to have SPM produce is a file
containing the ERP (averaged data) waveforms where there are no "bad
channels" (either because there were in fact no bad channels, or bad
channels have been re-created with interpolated data from neighboring
electrodes). Is this possible?
Thanks,
Robin
