Average tSNR values for rsfMRI datasets before and after applying the MPPCA filter (raw and denoised data). Here, tSNR values were computed as tSNR=mean signal intensity/variation over time, as described in Method 1, Figure 2(a). The SNR values (Figure 2b) were computed using Method 2, described in text. The error bars represent the standard error of the mean.
