[FieldTrip] Fwd: interpolation

[shlomit beker]

Hi Fieldtrippers,

We would like to use the ft_channelrepair(cfg, data) function.
However we don't understand how to load or convert the electrode positions
into FieldTrip.

We tried FT_READ_SENS and we looked in FT_DATATYPE_SENS, however there are
two positions variables described in this structure:

The structure for EEG or ECoG channels contains
     sens.label    = Mx1 cell-array with channel labels
     sens.chanpos  = Mx3 matrix with channel positions
     sens.tra      = MxN matrix to combine electrodes into channels
     sens.elecpos  = Nx3 matrix with electrode positions

what do the third field mean? what is the difference between the second and
the fourth?


our format is the attached.

Thanks a lot!

Omer and Shlomit
