hello I am not very familiar to Envi program, but I noticed that when I open an image the Envi displays it with some changes in DNs, I tested it for simple bitmap images and again it did the same, I want to know if there is a setting for this issues or not? and I have another question about striping artifact in Modis sensor, I like to know if Envi can remove this artifact or is there any sample code in IDL for removing this artifact? Thanks in advance P.s: i use ENVI 4.6.1
