Hi,
I would like to see if there’s a quicker way to do a third-level analysis than doing each cope separately, as a few posts I’ve read here suggest.
I have 2 runs / condition. I do a first-level fixed analysis for each run separately, and define EVs and contrasts here. I then do a second-level fixed analysis to join the output from the 2 runs of first-level analysis. This second-level analysis passes on the contrasts from the first level – i.e., I only have one .fsf file, not one for each COPE.
For the mixed third-level analysis, however, I cannot do one analysis – I have to do an analysis for each COPE separately. If I try to select the second-level .gfeat directories, I get an error saying “Warning: the first selected FEAT directory contains no stats/cope images”.
Do I have to analyze one COPE at a time, or can I do the 3rd level analysis for all of the copes at once like the second-level analysis?
Thanks!
Steve
