    I am processing multiple Landsat data for my research. I would like to perform dark object subtraction on each image then calculate NDVI from the output. Does anyone know if there is a way of grabbing the bands from the dark object subtract result and use them in the Band math expression? I have already done the dark object subtract part but I need to continue with the NDVI calculation. M

    Do you mean that you want to use programming to do this? Are you using DARK_SUB_DOIT? All ENVI routines include an output parameter called 'R_FID' which is the returned FID from the process. This contains the FID of the newly created file. You could then pass this to NDVI_DOIT.
