i’m trying to do atmospheric correction for this purpose, for this purpose i have install the sen2cor from plugin menu. but it does not working properly 'attribute error ’ popup please tell me how to solve this problem .
i also wanted to know where the output file will be saved , because when i open the sen2Cor only the diagonal of ‘source product’ is available.
It seems a problem with the metadata format. What product are you using as input? Is it an original product downloaded from ESA Scihub? The source product in your screenshot seems to be modified (at least the name, with the ‘-’ character).
On the other hand, sen2cor creates the output in the same folder as the input.
