[Qgis-user] Raster -> Merge (gdal_merge) failure

[Julio Cesar Canales Delgadillo]

Hi Nick,

I had the same problem with Qgis 1.6, some gdaltools work very well but 
by using others (like merge) I get an error message saying that qgis 
can't find some modules, they are there (but I don't know if they are on 
the wrong place). Anyway, I solved the problem by constructing a vtr of 
the rasters I want (this tool works fine) and then I transformed the vtr 
to another format I needed (this one also works very well). I know that 
this is not very elegant solution but it could be useful if you can't 
wait for long.

Cheers
