I have to do summation or integration of 37 bands of an hyperspectral
image in IDL to get final none output image. I tried with total
command but its not giving any result. Please help me as I am new in
this field.

Hi
try something like this
outdata = yourdata[*,*,0]
FOR i = 1, N_ELEMENTS(yourdata[0,0,*]) -1 DO BEGIN
outdata = outdata + yourdata[*,*,i]
ENDFOR
maybe there is a faster way to do it, but i am not aware of.
cheers,
corinne
