[GRASS-user] v.dissolve and r.cost problems

[Paolo Cavallini]

Hi all.
I cannot get a result from v.dissolve:

v.dissolve input=regiao at nuovo layer=1 column=REGIAO output=reg_diss
dbmi: Protocol error
Cannot open select cursor: SELECT cat, REGIAO FROM regiao ORDER BY REGIAO
Unable to open vector map on topology level 2
Table linked to vector map does not exist
Vector map not found in current mapset

This happens on a specific column. The same shp dissolves well with
fTools from QGIS.

Furthermore, I launched r.cost on a  295 rows, 378 cols matrix, and it's
taking > 1h, whereas I did the same previously and it ran in tens of
seconds.

 6.3.0.1-gfossit20090216-1
Any hint? Thanks a lot.

Thanks.
