Hi Bo
Look forward to our exchanges.

My problem is we do not have any fundamental scientist in that field in Malaysia,so I would suggest a small group of Cuban scientist(2),one or two of our clinical scientist to combine,we will invite our collegues from physics and mathematics from the whole of Malaysia.I need to prepare a budget early for this.the participants will have to pay for the course.DrJafri

Dear Pedro,Welcome,yes,I hope to have a 2011 summer or autumn course in basic signal analysis for students.postdocs in USM next year.Any ideas?Our fundamental is weak we are using the MEG mainly for epilepsy and neurosurgical work.
