Arguments

task_path	a task-level directory. The subdirectories of task_path should be subject directories, that begin with the pattern [0-9]{3}[CLPX], and these subject directories should contain experimental blocks.
partial	a vector of integers used to select some of the subdirectories. Used to partially load the set of sessions for the task, in order to prototype code or test the function. Default is NA.
