I'm trying to mask cloud cover of multi-spectral Landsat 5 image containing bands 1-7 that have been preprocessed using dark object subtraction and Landsat calibration.
I am using the fmask tool in ENVI5.5 and keeping all default parameters; Kernal Size 7 and Cloud Probability Threshold 22.5 as shown in the first PrintScreen below.
However when I try to run I get Error:
Attempt to subscript list with index 0 is out of range (Second printscreen).
How do I overcome this error to produce a cloud mask?
