If the source reconstruction<br>> is not aligned to your MRI, probably some ingredient for the source<br>> analysis was also misaligned. Could you see whether your source model,<br>> volume conduction model, and sensor definition are all in alignment?<br>> (See here http://fieldtrip.fcdonders.nl/faq/how_can_i_check_whether_the_grid_that_i_have_is_aligned_to_the_segmented_volume_and_to_the_sensor_gradiometer<br>> )<br>> <br>> Regarding (2): typically I would use cfg.taper = 'dpss' (the default)<br>> and then choose a combination of cfg.foi and cfg.tapsmofrq that yield<br>> the frequency band of interest. E.g. cfg.foi = 20 and cfg.tapsmofrq =<br>> 8 gives you a frequency band ranging from 12 to 28 Hz.<br>> <br>> Best,<br>> Eelke<br>> <br>> On 5 December 2013 20:32, Azeez Adebimpe <ayobimpe2004@hotmail.com> wrote:<br>> ><br>> > hello,<br>> ><br>> > 1.
