I have phr1a and phr1b images (Pleiades) and I need to make atmospheric correction. First, I tried to do this by using Envi FLAASH. by the way, I tried also ERDAS atcor but there was also same conversion problem. I did radiometric correction but I couldn't do atmospheric correction because every time the software has the error of ACC error:convert7. Does anybody have any idea how to overcome this problem?
