Define 'min/max spatial/temporal' resolution #2

Open TimVanMourik opened 5 years ago

TimVanMourik commented 5 years ago

The squares/convex hull for imaging methods that we need to compute need some definitions. The corner points basically define the minimum and maximum spatial and temporal resolution, but what does that mean? Discuss.

minimum spatial resolution (millimetres)
maximum spatial resolution (millimetres)
minimum temporal resolution (seconds) *
maximum temporal resolution (seconds)

NOTE: definitions will be updated based on discussion below.

I agree to stick with those SI unit.

Several issues that we might encounter:

converting for modalities that don't necessarily use those units (see multi unit recording where we have number of neurons but same for patch clamp or others)
non isotropic data: do we take the smallest dimension of the voxel or do we somehow convert that to isotropic ( e.g [voxel volume]^(1/3) )

TimVanMourik commented 5 years ago

That's indeed the prime motivation of this issue :) Added problem:

It sounds reasonable to define the 'smallest voxel' but then what does the 'largest voxels' mean? Same question for temporal resolution.
