[FieldTrip] Creating Leadfield using BEM

[B.Mouthaan at neuro.umcn.nl]

Dear all,

I also received the following information on my command screen


the input is timelock data with 31 channels and 500 timebins
using headmodel specified in the configuration
using electrodes specified in the configuration
Warning: Duplicate data points have been detected and removed.
 Some point indices will not be referenced by the triangulation.

determining source compartment (3)
projecting electrodes on skin surface

642 dipoles inside, 0 dipoles outside brain

Maybe this brings us more to the solution.
