Hi all,

We are having a problem with the threshold display for 32 bit images.

Example.
An image with a wide range of values, we set the threshold to 1-Infinity, the whole image appears in red, but when we hit Apply and set "Background to NaN", the proper pixels are set to NaN on the image, making what the preview was showing inconsistent.

We had a worse problem where an image was rescaled to fit in the 0-1 range of values. The Huang method was giving a preview that looked promising but upon hitting Apply, the shape of the mask vas very different from the one that the preview.

What is behaving differently when we hit preview and when we actually perform the create mask operation in 32-bit images?

Best

Oli
