Aligning matrices to a common space

In this example, we plot the trajectory of multivariate brain activity for two groups of subjects that have been hyperaligned (Haxby et al, 2011). First, we use the align tool to project all subjects in the list to a common space. Then we average the data into two groups, and plot.
