Hi Paolo and Victor, The expression needs to be in the form:
output_name = input_name [operation] [constant or another input_name] So, in your case: dtm2 = dtm*2 But it still has problems, specially in Windows: https://hub.qgis.org/issues/6894 It would be great to have r.mapcal full operational in Processing. Best regards, Pedro Venâncio 2016-10-22 18:11 GMT+01:00 Victor Olaya <[email protected]>: > looks like the formula (dtm*2) is correctly passed to GRASS, but it > complains that is wrong.
