    how to convert SPOT 7 DNs to Top of Atmosphere (ToA)Re?ectance using FLAASH atmospheric correction in ENVI 5.1? according to SPOT6&SPOT7 imagery user guide, there are converting digital count to TOA Radiance formula and TOA spectral reflectance formula. but I have not seen any application using FLAASH atmospheric correction.

    First you need to convert to radiance using Radiometric Calibration and the 'FLAASH Settings' option. Then you can use FLAASH. SPOT-7 support was added in ENVI 5.2SP1. I would suggest you upgrade to the latest version of the software.
