importing 306-Vectorview dataset

[Jon Houck]

Hello,

Kimmo has a partial Windows version of the MEG-PD toolbox posted on his site
now.  I've used it successfully with 306-channel data in the old 4D Toolbox,
but haven't tested it with Fieldtrip yet.  It may be of some use here.



Regards,

Jon Houck
