Description

SNS scientist reported issue using scitiff image in ImageJ where it fails to scale when ROI is NOT selected.
ImageJ should be able to compute min/max but it fails to do so unless there is a ROI selection.

My hunch is that it's because of the second/third channels (variances/mask) but I haven't reproduced it myself.

We should either find a way to avoid this problem in ImageJ or inform users how to avoid this issue.

Research direction

Start by reproducing the ImageJ autoscale failure with a scitiff image both with and without an ROI selected. Compare behavior across the primary image and the second/third channels, then determine whether the project should prevent the failure or document a user workaround; done means the failure is understood and one of those outcomes is established.
