Hi - the concatenated timeseries are in the melodic_mix file - but
these are not the result of the first stage of dual regression
(MELODIC doesn't run that for you) - they are the result of 'back-
projecting' the (reduced-space) ICA timeseries - and this is not
recommended.
If you would like to beta-test the dual-regression script, let us know
and we can send you the link.
Cheers.
