Data quality check:
A movie of the physiology traces of the 900-subject release Human Connectome Project (HCP) and decisions about whether data quality was sufficient for use was part of the supplemental material of another paper and can be found here. These traces and decisions are the basis of selecting 440 of the 900 subjects for analysis. The data analyzed are exactly the data examined in this paper.
Movie 1: (.mov - 1.4 GB)
This movie illustrates each run of the 440 analyzed subjects. At top the first panel shows head position traces (gray) and motion traces (red= FDfiltered,4-TR, light red = FDfiltered), 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 2 (.mov - 8 MB)
These movies show the 15 deep breaths of Figure 5. 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.
Grayplot data for all subjects: (.zip - XX GB)
This download contains a readme and a Matlab .mat file containing the elements of gray plots for all subjects, and a few other things. For each analyzed subject, a structure contains all physiology data, important derived measures (ENV, RV, and RVT) and also unvetted heart rate traces, random downsamples of gray and white matter voxel signals in minimally preprocessed and post-FIX-ICA images, DVARS of those images, and motion estimates (FDoriginal, FDfiltered, and FDfiltered,4-TR).
