Greetings, I have a multi-band image, that I would like to mask based on criteria from each band of the image. I use the ROI_THRESH_DOIT to create the ROI for each band separately. Now I would like to intersect the regions for all the bands of the images to create the mask. How can I do so programmatically?

There is no routine to do this in ENVI. You could create an image of the same dimensions as your multiband file and then set the pixel values to 0 or 1 using a series of WHERE statements.
