ENVI will not allow me to perform radiometric calibration (Toolbox>>Radiometric Correction>>Radiometric Calibration) unless my .bip hyperspectral image contains offset and gain values for each and every single one of its 21 bands.
I need to find a way to introduce such values. I tried to do so through a couple of different dialog boxes ("Toolbox>>Radiometric Correction>>Apply Gain and Offset" & "Toolbox>>Raster Management>>Data-Specific Utilities>>Edit ENVI Header") but when I try to start radiometric calibration the same exact error keeps popping up.
I know your need after read your job description, we confident can solve it, but I should know what satellite or sensor of the hyperspctral, we can discuss together,
I hope you choose me to finish your work,
Best regard,

Have been working on hypersperspectral datasets for 5 years now.
After reading the problem I would suggest you try the following tips first;
i) If you have successfully entered the gain and offset values please check the units of the output image if they have converted to radiance (Watt/m2 * steradian * µm)
ii) If there is an issue in applying gain & offset values, convert your image to .bil format then try.
Still facing the problem? Send your data with metadata file I will fix the issue.
Thank you.
