Introduction: RNA sequencing (RNA-seq) data from space biology experiments promise to yield invaluable insights into the effects of spaceflight on terrestrial biology. However, sample numbers each study are low due limited crew availability, hardware, and space. To increase statistical power, RNA-seq datasets different missions often aggregated together. this can introduce technical variation o...

larger AIF for the three correction methods: 1.Magnitude averaging (black), 2. Rician correction (red), 3. Complex averaging (green). Figure 2. Gad concentration curves converted from the AIF signals (larger ROI) using different correction methods for SNR = 1.7. The true and complex averaging curves overlap. Figure 1. The relative errors (mean±SD) of the baseline signals to the true value for t...
