    Hi Roohi, If you are using Hyperion tool to convert your L1R/L1Gst data to Envi standad,then it require first 7 bands to run FLAASH. So, before running FLAASH remove first 7 bands from Bad Band Lists (Edit Envi Header) and then run Flaash on that. After Flaash, put those bands back under bad band list (on flaash output). -Anuj Singh
