Im trying to run FLAASH with an airborne hyperspectral sensor. This sensor has a spectral resolution of 28 nm in the water absortion bands, so I have decided not to aply the water retrieval algorithm. I supose that I have to define a hyperspectral channel definition file with the channel I want to use in the aerosol correction only: KT upper channels = { 30 31 32 33 34 35 36 37 38 } KT lower channels = 8  I get the next error: Problem: The FLAASH program exited with the following errors: ACC error: avrd: IDL error: ACC_CHANNEL_DEFN_READ:ACC error: One or more necessary definitions not found in file ******.txt ACC_AVRD ACC_HYPER2 ACC_ACC ENVI_ACC_EVENT ENVI_FLAASH_PROCESS_MANAGER IDLRTMAIN $MAIN$         When I aply FLAASH
