Hi. I'm new to this group, and I would have thought this was a FAQ,
but I couldn't locate it, so:

I am looking for a high-level language/environment for viewing,
editing, and manipulating physiological signals.  My signals tend to
be 1D waveforms like EEGs, but I often want to work with many
channels simultaneously.  I want to be able to view them on a
SPARC2 running OpenWindows 2, and to interactive things like cursor
movement etc.  However, I would also like an underlying highlevel
language for doing things like:
applying builtin or userdefined functions to signals: a=fft(b)
arithmetic signal manipulation;  signal3=(signal_a+signal_b)/2
etc., so that automated analyses could be done in batch.  A macro
facility would also be extremely useful.

Does anyone have any thoughts about such environments, prefarably PD
but commercial info would also be interesting.  At the moment, a lot
of the software interest seems to be on environments for image
processing, but there still seems to be a wide-open space for someone
to come in with a really good signal environment.

Thanks
