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

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

v.surf.rst input=punti_interpolazione layer=0 dmax=4.999977 dmin=0.999995
cvdev=cross_test zmult=1.0 tension=40. smooth=0.1 segmax=40 npmin=100 -v

DBMI-DBF driver error:
SQL parser error in statement:
create table punti_interpolazione.cross_test ( cat integer, flt1 double
precision)
Error in db_execute_immediate()

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.

It is bad - any scripts or Books written for GRASS 6.0 should work with
any GRASS 6.x.

If "-v" is obsolete it should be described as depreciated in the
flag->description and trigger a G_warning() before setting "-c" to be
true & then run the module as the user intended.

In this case there is no known documentation about it.
-v is reserved for verbose

Generally, it should be possible that authors correct things.

and there is a help option :slight_smile:
