Hi Juan,

On this example, ImageIntegration generates this message:

Code: [Select]
* Rescaling output image. Integration range: [-1.37814204e-03,8.56981397e-01]

However the ImageIntegration output is not in the full range [0, 1] as I expected, instead it is [2.931992e-03, 9.946846e-01].

Is this a bug?

Zipped folder, with all frames, LocalNormalization reference and results, Integration results and log, and process icons.

The negative pixels were generated by using a low median LN reference.

Hi Mike,

You are reading clipped statistics. Check the Unclipped option on the Statistics tool and you'll get minimum=0 and maximum=1, as expected.
