You must set the lower channels or let FLAASH automatically select them.

Normal 0 false false false MicrosoftInternetExplorer4 Hi I think I have same problem as vrgaliano@ugr.es but can’t figure it out Problem: The FLAASH program exited with the following errors: ACC error: avrd: IDL error: ACC_CHANNEL_DEFN_READ: Error in reading channel divination file U:\......\*.ers ACC_AVRD ACC_HYPER2 ACC_ACC ENVI_ACC_EVENT ENVI_FLAASH_PROCESS_MANAGER IDLRTMAIN $MAIN$ Is there one can help me with this? Thanks Salahuddin Ahmad   [QUOTE]vrgaliano@ugr.es wrote Hi everyone, I want to apply FLAASH to an airborne hyperspectral sensor image (AHS). The ASH has a spectral resolution of 28 nm in certain water absortion bands, so I dont want to apply the water retrieval algorithm. I have defined channel definition file only with aerosol retrieval channels: KT upper channels = { 30 31 32 33 34 35 36 37 38 } KT lower channels = 8 But Ive got the next error message: 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 $MAIN$ Is there any technical support which can help me?
