Blank Image After Terrain Correction

Maybe I find the problem. My data is a subset of original ALOS2 data, with the type of .dim。Maybe between the process of subsetting, some information is missing? Is that possible?

looks alright to me. The BEAM DIMAP format (.dim / .data) is the best to conserve all metadata.

After subsetting, please make sure that the data is correctly written (File > Save Product)

Dear ABraun, thank you very much for your reply. I have solved my problem. There are some problems with my source data, although not due to the format.
Maybe others having the same problem can change the data to test the cause of the problem.
Thank you, ABraun~
