Hi experts,
every time I try to open landsat-7 ETM+ data like this:
File>open external file>Landsat>geotiff with metadata
The scene bands appear in the available band list, but when trying opening any band I recieve the following error message along with a black image display:
ENVI Retrieve Data: An error has occurred during processing
Error:"Point_LUN: variable is undefined unit." the result may be invalid
I need your help in this problem
Thanks for all

Do these bands exist (with these names) in the same directory as the _mtl.txt (metadata) file you opened?
BAND1_FILE_NAME = "p172r045_7dt19991012_z36_10.tif"
BAND2_FILE_NAME = "p172r045_7dt19991012_z36_20.tif"
BAND3_FILE_NAME = "p172r045_7dt19991012_z36_30.tif"
BAND4_FILE_NAME = "p172r045_7dt19991012_z36_40.tif"
BAND5_FILE_NAME = "p172r045_7dt19991012_z36_50.tif"
BAND61_FILE_NAME = "p172r045_7dk19991012_z36_61.tif"
BAND62_FILE_NAME = "p172r045_7dk19991012_z36_62.tif"
BAND7_FILE_NAME = "p172r045_7dt19991012_z36_70.tif"
BAND8_FILE_NAME = "p172r045_7dp19991012_z36_80.tif"
It sounds like ENVI is trying to display the bands specified in the metadata but it cannot find them.

You are the best
I found that file names have been changed; and I rename them using the MTL file names
Now every thing works well
Thank you very much
