Hello Daniel,
What about using operator=contains and -r flag? Does that work?
You may also want to update to GRASS 7. Check the manual for v.select [0]

Ciao Umberto,
AFAIK, classification is multivariate on its statistical basis, so that's
why it will only take a group as input. If you only have one band, you may
want to extract some information from it, for example by using r.texture
module [1]. With those resulting new bands and the original on
nstead. This module has other issues
but is able to correctly identify space time datasets.

You should use t.rast.algebra (
