iCOR Atmospheric Correction for Landsat-8 error


I am processing Landsat-8 (Level 1) images and I made the atmospheric correction using iCOR plugin, with default parameters. I obtained a processed image completely black. I opened this image in QGIS and I did a band combination 432, receiving the image below.


I opened the bands one by one and I saw that the interval of each band was very short, very different of original image’s interval.

What could have happened?
In the case of some parameter configuration, what can I do?

Thanks for you attention!


The pixel type of ICOR output is float32, with values between 0 and 1.
So SNAP can’t display them well.
It shoud be possible to multiply by 10000 and select uint16 pixel type
