I have a problem using CONN, which I could not figure out by reading the Forums. I would appreciate it if anyone could help me.
In our study, each participant underwent two resting-state
fMRIs: once when sleep-deprived and once with full sleep. We wanted
to extract the denoised time series from CONN to perform DCM in
SPM.
I specified two conditions (sleep dep/full sleep) based on this
blog (for pre/post design here (https://andysbrainbook.readthedocs.io/en...)).
(https://andysbrainbook.readthedocs.io/en...) But
the "data" time series in
results/preprocessing/ROI_Subject*_Condition001 and
ROI_Subject*_Condition002 are the same!
I read in forums, that we can have condition-specific time series
with running
"w = max(0,conditionweights{1});
idx = find( w>0 );
data_reduced = cellfun(@(x)x(idx,:), data, 'uni',0);
w_reduced = w(idx);"
But I am not sure this is okay in my case since I have resting state data. Could you please share your thoughts with me?
Best wishes and thank you for your time,
