Hi,
I'm trying to use the function "runica" from the eeglab toolbox to decompose a fairly large data set. Now I've been testing it on a small sample of the data (5 channels) to figure out what do do but have hit a snag with the outputs.
From the command:
[weights,sphere,project,activations]=runica(datiatt([1:5],:));
I am getting the following outputs:
>Weights == 5x5 double, -6.485min, 8.232max
>Sphere == 5x5 double, -0.0225min, 0.0323max
>Project =[2.041472649833849e+04,1.057366806435951e+03,8.424862489971001e+02,5.5
08867487460723e+02,86.325649879637750] , 86.3256 min, 2.0415e+04 max
>Activations== [0.521181380438761;-
0.503483128865776;0.168416662178569;0.087787753657055;-
0.278149228696979], -0.5035 min, 0.5212 max.
The issues I'm having
- Activations is not equal to 128*length of datiatt matrix.
- When trying to compute the unmixing matrix so that I can view the components and re-run my psd analysis I am getting the error message:
W=weights*sphere "matrix dimensions do not match".
Without being able to create 'W' I can't go any further with the analysis.
Does anyone have any helpful hints or suggestions?
Thanks
