For each anatomically-defined region of interest, the reliability of between-day and within-day activation of each task. Between-day reliability is reported averaging across both runs, and for each run separately. Within-day reliability is reported for day 1 and day 2 separately. A negative ICC is interpreted as indicating a reliability of zero (Bartko, 1976). GC=gender classification; EI=emotion identification; EM=emotion matching; LAmyg=left amygdala; RAmyg=right amygdala; sgACC=subgenual anterior cingulate cortex; ICC=inter-class correlation coefficient; CI=confidence interval.
