[FieldTrip] eLORETA source analysis

[tibor.auer at gmail.com]

Dear Community,

 

I would like to perform an eLORETA source analysis, however, I am unsure
about the steps. 

 

I am working on the LEMON data
<http://fcon_1000.projects.nitrc.org/indi/retro/MPI_LEMON.html>  including
62-channel EEG experiment at rest and structural (T1-weighted) MRI of >200
participants.

 

I have preprocessed the EEG data and performed timefrequency analysis on the
2-second-long epochs with configuration:

*	method: 'mtmfft'
*	taper: 'hanning'
*	foi: [0.9766 1.9531 3.9062 5.8594 7.8125 12.2070 15.1367 20.0195
24.9023 32.2266 40.0391 60.0586 69.8242 80.0781 95.2148 109.8633 120.1172]
*	pad: 2.0480
*	output: 'pow'
*	keeptrials: 'no'
*	trials: [233×1 double]

I have also processed the MRI images and normalised-segmented them using
SPM12's unified segmentation outside FieldTrip.

 

I would appreciate any help including code snippets, pointers to (order of)
functions or specific and detailed tutorials.

 

Kind regards,

Tibor
