[GRASS-dev] [bug #4557] (grass) problem with v.surf.rst cross validation

[Maciek Sieczka via RT]

Marie,

Indeed in Grass 6.0x for turning on the CV there is '-v'. In the newer Grass
6.1, as Helena says, there is '-c'.

Question for devs - is it good that we have the flags not preserved between
6.0 and 6.1?



Getting back to  Marie's problem

Marie,

I don't why v.surf.rst is trying to create a table
'punti_interpolazione.cross_test' when your requested CV vector name is
'cross_test'. Especially that the dot in the table name is illegal
(http://grass.itc.it/grass61/manuals/html61_user/sql.html).

Moreover I can't reproduce the error in my Grass 6.02 instalation
(2006_01_28), using exactly the same command as you did. Are you sure you
pastes *exactly* the command you used, and that there was no dot in 'cvdev'
name by nay chance?

Can you try the latest 6.0x version, which is 6.02, and let us know how it
works? 6.0 is over a year old now.
