1. I did PPI on an MNF file and I am getting a chequered image. is that normal because i heard we get a bit file image and i hope its nothing crazy if yes help me :D 2. then going to create a roi from the ppi. http://geol.hu/data/onlin...erest.html#wp1062570 I did the step only once, that means i have only one band? (i put threshold from 1-506) :D 3. So after PPI and roi, I am going to o nD visulaiser. a. If input of nDvisualiser is the output of MNF then i get the good old error " the input file must contain atleast 2 bands" b. so try to upload the roi file by Exporting ROIs to the n-D Visualizer http://geol.hu/data/onlin...erest.html#wp1066046 I get a single band instead of this beautiful picture I was thinking of uploading screenshots but imageshack and photbucket is crashing in my comp :( So help me guys as much you can, i will try to upload the images once i am at home.
