iCOR Atmospheric Correction for Landsat-8 error

Hello!

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!

Hello

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

Please show me the operations to multiply by 10000 and select uint16 pixel type
