[Eeglablist] pop_reref to exclude some channels for average reference

[Sue Peters]

Dear EEGLab Users,

I am using this function, pop-reref, for an average reference of 124
channels.  However, I would like to exclude 16 of these channels from the
average reference calculation. I have used the 'exclude' input to specify
the exclusion of these channels:

EEG = pop_reref( EEG, [], 'exclude', [17 43 48 49 56 63 68 73 81 88 94 99
107 113 119 120]);
%16 channels removed leaving 108 for av ref

I've also tried just selecting specifying the 108 channels directly:

 EEG = pop_reref(EEG, [1:16 18:31 33:37 39:42 45:47 50:55 58:62 65:67 70:72
75:80 83:87 90:93 96:98 101:106 108:112 115:118 122:124]);

But I'm not sure that either is working correctly, and am not sure how to
confirm that the function is actually averaging the 108 channels, and using
these as the reference.

Any thoughts are welcome!

Thanks,
