[FieldTrip] denoise_pca error

[Ashley Greene]

Hello all,

I hope someone will be able to help with this. I'm trying to run the
denoise_pca function on data after preprocessing, but I continue to get the
following error:

Error using  ./
Matrix dimensions must agree.

Error in ft_denoise_pca (line 193)
    s1   = s./max(s(:));

Could it be due to the use of the default for refchannel? Forgive me for
asking such simple questions, but how do I go about choosing the reference
channel? Do I just choose the cleanest channel from that particular set of
preprocessed data?

Thanks in advance,

Ashley
