Standard fMRI preprocessing steps were applied using the FSL software (www.fmrib.ox.ac.uk, version 5.0.9) and custom MATLAB code (BRAMILA pipeline v2.0, available at https://git.becs.aalto.fi/bml/bramila/). Briefly, EPI slices were firstly corrected for slice timing differences. Volumes were then corrected for head motion using MCFLIRT and coregistered to the Montreal Neurological Institute 152 2mm template in a two-step registration procedure using FLIRT: from EPI to participant’s anatomical image after brain extraction (9 degrees of freedom) and from anatomical to standard template (12 degrees of freedom). Further, spatial smoothing was applied with a Gaussian kernel of 6 mm full width at half maximum. To remove scanner drift, a 240-sec-long Savitzky-Golay filter (Çukur, et al. 2013) was applied. Furthermore, time series were also filtered with a high pass temporal filter at a cut-off frequency of 0.01 Hz. To further control for motion and physiological artefacts, BOLD time series were cleaned using 24 motion-related regressors, signal from deep white matter, ventricles and cerebral spinal fluid locations as described in Power et al 2012.
