Dear FSLroots,
i used T-ICA to perform analysis across subjects and obtain informations about correlation between time course and model. Each subjects have 4 runs. My steps:
1) preprocessed every runs for each subject( bet, motion correction, spatial smoothing, high pass filter and registration).
2) for each subject, i concatenated the 4 runs and then i built an unique model to use for the correlation with time courses extracted from ICA components.
3) then i started the analysis with this command:

melodic -i list_subjs -o tica -v --nobet --bgthreshold=10 --tr=2.0000000000 --report --bgimage=bg_image -d 40 --mmthresh=0.5 --Oall -a tica --Tdes=tica.mat  --Tcon=tica.con

At the end, i obtained only 2 components that correlate with model and these components are very different compared with the Feat results. I attach to you the time course of one component. Is it right that the time course is "not linear" like this ? Most of the components have time courses similar to this one.

Thank you very much. Regards
