Hi, I'm having problems calibrating some Landsat ETM+scenes downloaded via EarthExplorer. The imagefile contains 9 bands (B10, B20, B30, B40, B50, B61, B62, B70 & B80) but ENVI's "Spectral --> Preprocessing --> Calibration Utilities --> Landsat TM" gives an error message saying it can only handle up to 7 bands. I've tried to do a spectral subset of 7/9 of the bands and i've also tried and "restacked" the images to contain only 7 bands. With the restacked images i can begin the calibration (selecting the ratio button ETM+ 7) but ENVI gives an error message telling me that it can't read the Gain/Offset data, although the MTL-file is copied into the same folder. Any suggestions on how i can solve this? (Preferrably without doing everything manually in band math..) I'm using ENVI 4.3. Any ideas are welcome, thanks for reading. // Marcus
