Hi,
I'm using the shapefile of the GADM database of Global Administrative
Areas (http://www.gadm.org), but the subdivisions of some countries
(such as Spain, Slovenia and others) are too small. In order to get
divisions that are more evenly sized among all countries, I need to
dissolve sub-regions to regions, but only within some of the
countries. Is there a way to use a "conditional dissolve" on only some
selected countries?
Cheers

In GRASS, "v.dissolve" is just a frontend to "v.extract -d ...". Since
the latter has
a "where" parameter, you could try with that.
Please report, perhaps it makes sense to add the "where" parameter to
v.dissolve then.
