Hi Moritz, We are about to compare results from the two addons... Unfortunately, I missed some details, so the manual page is not online yet (issues should be fixed now).
The main additions, compared to i.spec.unmix are - three alternative endmember detection algorithms - (at least) two additional algorithms for spectral unmixing (Unconstrained least squares and fully constrained least squares (with the latter, pixels values in the resulting maps sum up to 1). I should probably also mention, that i.pysptools.unmix allows to write out detected end members in a format that i.spec.unmix understands. So the modules can be complementary...

Great, thanks a lot ! How does it compare to i.spec.unmix ? I assume it adds more algorithms ?
