    Hi I am a new IDL user and I am working with a multiband image. I would like to identify in each of the bands all pixels with a certain value, how can I do it? Thanks for your help

    You could use a WHERE statement to find the values in your array.  There is an example in the IDL help on how to use this for a 1-D array.  For multiple bands, you could use a FOR loop to loop through each band and find the values of interest.
