    Hello,

    I have a band ratio image and I would like to save the image as a geotiff and just include the 90th percentile.
    Do you have an idea to do that precisely without using Interactive Stretching ?

    Thank you,

    Ludovic

    Do you mean you want to mask all of the pixels below the 90th percentile? I would use Build Mask and specify a Data Range to be 'on' or the 1s in the mask while the rest of the pixels are 'off' or the 0s in the mask. Then you can apply the mask to the file using File->Save As and export to TIFF.
