RE: ROI Mean Time Series
Hi Sanja,
Yes, you are exactly correct, the variable "data" in the ROI_Subject#_Condition#.mat files contains the BOLD timeseries after the denoising step (to be used in the first-level analyses). The variables d1data/d2data/dbdata contain, respectively, the first-order derivative, second-order derivative, and band-pass filtered timeseries using a series of pre-defined filter-banks (none of these are used in the standard connectivity analyses, i.e when using a single dimension per ROI, no temporal-derivatives, and no filter-banks for each source/ROI defined in the first-level analysis step). The additional variable "names" contains the associated ROI names for each element of data.
Hope this helps
Alfonso

Hello,
I am trying to find where exactly denoised ROI time courses are stored, and it is not clear to me what the following variables in \results\preprocessing\ROI_Subject###_Condition###. mat represent:
d1data
d2data
data
fbdata
Would the time courses that are used in 1st and 2nd level analyses be the ones in the 'data' variable?
Thank you.
