[GRASS-user] Re:Using v.colors in WinGRASS

[Luisa Peña]

Hi
Ok here it goes.
1- I needed to remove .py from v.colors and v.db.addcolumn scripts in order
to run them in GRASS6.4.0.
2- v.info teste12

3- If I select an area I get this info:
East: 638957.32135
North: 9327883.257322
Map: teste12
Mapset: Regional
Type: Centroid
Id: 201
Layer: 1
Category: 2
Driver: dbf
Database: C:\ISdata/Brazil/Regional/dbf/
Table: teste12
Key column: cat
cat : 2
label :

4- then I did:
v.colors map=teste12 at Regional column=cat color=aspect

And I got:
ERROR: Column <cat> is not numeric
This is weird because, I get CATEGORY values.

5- Then I decided to add GRASSRGB column like this
v.db.addcolumn map=teste11 at Regional columns=GRASSRGB varchar(11)

and I got the following error
-: No such file or directory
ERROR: Unable to add column <GRASSRGB varchar(11)>.

Can anybody give me an hand on this?
Thanks
