I am using ENVI 5.1 on Windows 7, 64 bit. The FLAASH atmospheric correction module on my computer is generating an error that causes IDL to freeze and crash. I want to correct 2014 RapidEye data purchased from their vendor. When I go to apply FLAASH corrections, the Spectral Library Viewer comes up, loading rapideye.sli. This freezes and causes the crash. The error is Intel(R) Visual Fortran run-time error. "forrtl: severe (9): permission to access file denied, until 99, file 'C:\Users\....\IRECLN_FILE'......... Stack trace terminated abnormally." When I went to C:\Program Files\Exelis\ENVI51\classic\filt_func\ and loaded rapideye.sli the Spectral Library viewer doesn't display a curve. Is the error with the sli file, or some other part of the FLAASH correction workflow? Thanks.
