Dear fieldtripers,

I want to use the music algorithm for source localization on SEP data(somatosensory evoked potentials) and I would like some help.:
Those are my questions
1.The music algorithm needs a number of components (i.e dipoles) and I am wondering where to specify that.
  For the moment I ‘ve just edited the music.m file for that, but I was wondering if there is a more efficient way.
2.Does the algorithm needs a prestimulus part of the data for comparison that will be used in the covariance matrix?
3. How do I plot the results for music algorithm if I am only interested in one dipole activated? Should I set a roi before?
Thanks in advance
Nadia Kalogianni
