grass.mapcalc("$upstream_shreve = if(${upstream_part},${shreve})",
                  upstream_shreve = options['upstream_shreve'],
                  upstream_part = options['upstream_part'],
                  shreve = options['shreve'])

but that isn't working... I don't know whats excaclty the problem....
