[Eeglablist] Running AMICA

[Jason Palmer]

Hi Zohre,

 

The matlab programs amica_ex.m and amica10.m are mainly for demo purposes.
If you use runamica12.m (http://sccn.ucsd.edu/~jason/amica_web.html ) to run
one of the binaries, the following should load the output into eeglab:

 

                >> [EEG.icaweights, EEG.icasphere, mods] =
runamica12(EEG.data(:,:));

                >> EEG = eeg_checkset(EEG);

                >> eeglab redraw

 

Runamica12.m tries to figure out if you're running pc, mac, or linux, and
use the appropriate 32 bit or 64 bit version (assuming you downloaded one of
these from the links on the webpage.)

 

Best,

Jason

Hi all,

 

I am trying to run AMICA algorithm in matlab on EEG data.

I found amica_ex.m and amica10.m (which is older).

I also used this command to get the components, which I found in the websie:

 

                EEG.icawinv=pinv(EEG.icaweights);
                EEG.icasphere = eye(size(EEG.icaweights));
                [EEG.icaact] = eeg_getica(EEG,1:EEG.nbchan);

 

however, it doesn't work and I don't have any idea to work with this
algorithm and get

independent components as outpt.

 

can anyone help?

 

Thanks all,

zohre
