Hi Kelly,

I don't think voltool lets you do more than two at a time. I typically
use gridData (which comes with MD Analysis, or can be installed
standalone;!!DZ3fjg!tU_dHGGRhY-VZCgTcsTcIn8TmIDJtO3r0SNP5heHdCWkdMqsuvdXhzDFSJl4CKsoHw$ ),
convert the map to a numpy array, and do my averaging in numpy-array
space. So long as you take care that the centers/axes for the grids are
aligned, you can just operate on the arrays directly.
