[FieldTrip] SAM option in ft_sourceanalysis

[Elena Orekhova]

Dear fieldtrippers!

I tried to use SAM beamformer for the EEG analysis,
But I have got en error (see below).
I guess that there is a bug  in ‘beamformer_sam’at line 112.

I wonder if ‘SAM’ option works at all?  Did anybody used ‘SAM’ in ‘ft_sourceanalysis’?

Thanks,
Elena
