FAQ: Content of d2nd

[behinger]

I got asked whats in d2nd:

tmp = load(fullfile(projectFolder,'cache/n400_2nd.mat'));
d2nd = tmp.d2nd;
What is stored in tmp.d2nd matrix defined above ?!

And of course it is something I forgot to include in the tutorial (which will get a revamp with simulated data very soon!)

LOOP OVER SUBJECTS
       LOAD SINGLE SUBJECT UF_CONDENSE OUTPUT

       % first subject: initialize d2nd (2nd-level analysis)
        if isempty(d2nd)
            d2nd = ufresult;
            d2nd.subject = subj;
            d2nd.unfold= struct();
        else
            d2nd.beta(:,:,:,end+1) = ufresult.beta;
            if isfield(ufresult,'beta_nodc')
                 d2nd.beta_nodc(:,:,:,end+1) = ufresult.beta_nodc;
            end
            d2nd.subject(end+1) = subj;
            d2nd.unfold(end+1) = ufresult.unfold;
        end
