[FieldTrip] Fieldtrip dipole fit

[Rita Martins]

Hi Jan Mathijs,

Thank you for your help.

I'm using function api_ica_estimate (
https://bazaar.launchpad.net/~arabica-core-dev/arabica-ica/1.0/view/head:/api_ica_estimate.m)
in order to obtain the cluster mixing matrix of the components. How could I
import this data to fieldtrip so I can do the dipole fitting?
I’m having some trouble understanding what is actually needed from a data
point of view.

Thanks in advance.
Best regards,

Rita Martins
