    Hi,

    I'd like to map minerals with MTMF, or SAM. I use spectra from the USGS spectral library, but there are several spectrum for each mineral.

    Is it possible to calculate a mean spectrum from 5-6 spectra of a same mineral ?

    Thanks,

    Ludovic

    You can use a tool such as Spectral Math:

    Display the spectra you want to combine into the mean, and use a variable for each spectrum. For example:

    (s1+s2+s3)/3
