Compute ROI-to-ROI functional connectivity of the salience/cingulo-opercular network for correlation with structural connectivity of this network in healthy older adults (with and without subjective cognitive decline).
-
Looping BASH scripts to apply FSL functions (v.6.0.1) across participants to obtain ROIs' time courses.
-
The ROI-to-ROI functional connectivity was computed in R (see the corresponding R scripts).
-
The script numbering reflects the order of analysis steps followed.
-
ROIs were obtained and selected from the 360-area MNI map derived from the multimodal parcellation of Glasser et al. (2016).
-
ROIs were visually inspected to overlap with the anterior salience network map of Shirer et al. (2012).
-
ROI time course extraction was run on Ubuntu 16.04.5 LTS (Xenial Xerus) with FSL v.6.0.1.
