We used five mother wavelets which have been used in previous fMRI literature, including db2 (Bullmore et al, 2004;Salomon et al, 2011;Zhang et al, 2016), bior4.4 (Laine, 2000;Van De Ville et al, 2003;Mutihac, 2006), morl (Chang and Glover, 2010;Bajaj et al, 2013;Omidvarnia et al, 2017;Yaesoubi et al, 2017), meyr (Behjat et al, 2015), and sym3 (Khullar et al, 2011). The traces for the five wavelets are shown in Supplementary Figures S1-S5, respectively.…”
