Movie S1 (.mov - 1.4 GB)
This movie illustrates each run of the 444 analyzed subjects. At top the first panel shows head position traces (gray) and motion traces (red), the second panel shows DVARS traces before (light green) and after (dark green) FIX-ICA, the third panel shows in blue the respiratory belt trace and the derived ENV (red), RV (blue) and RVT (black) traces. The fourth panel shows as a grayscale heat map all in-brain time series of the image before and after FIX-ICA (as successive frames of the movie).
Movie S2 (.mov - 16 MB)
These movies show the 15 deep breaths and 15 bursts used to summarize the patterns. 15 gray plots for each pattern are shown, from different subjects, with vertical red lines denoting the 90 seconds of data examined and t = 0.
Movie S3 (.mov - 130 MB)
These movies show the gray plots of the 21 subjects in each group of scan types examined at the end of the paper. Burst scans have prominent bursts in most or all scans and little to no evidence of single deep breaths, single deep breath scans have prominent single deep breaths in most or all scans and little to no evidence of burst patterns, and clean scans have minimal or no evidence of either pattern in all scans.
Table S1 (.xlsx): Table of 782 HCP variables and the significance of the 3 real groups and 50 random groups among 10,000 permutation tests. All of these variables are shown in the heat maps in Figure 16, and select variables are listed in Figure 16. Additionally, here is a list of variables associated with each group, and similar lists for 3 of the random groups.
