    Hi all, I know that we can set a background value when building a stack, but how do I do it when building a stack? My input layers lave different resolutions and I do want to use bilinear interpolation. But I need ENVI to avoid interpolating the "data ignore" values. I tried changing the header in my input layers, with no success. Thanks, Naiara.

    Yeah, I'm afraid that ENVI doesn't use the data ignore value in the header of images when it does layer stacking.  The only way to avoid having those background pixels interpolated into the new pixel values, is to use a nearest neighbor resampling method.
