I have a quick question on basic thunder i/o. I have imaging data that was already pre-processed in python and lives as a [t, x*y] .npy array. It seems the most natural way to load this would be something like: loadImages('fname', [t,x,y], inputFormat='stack'). When I do this, the loaded data shows nrecords=1. I'm probably missing something obvious - but how can I correctly load t images from a .npy file? Thanks!
