[GRASS-user] Set rasters with inf values to nodata

This is the first time I've seen such Max values too.  But I have been able to solve my problem by converting these files to Arc/info ASCII Grids and replace all "1.#INF" to my nodata value.  I'll see if anyone on the GDAL ML can help me.

Honestly, I have never seen such Max value.

Maybe a GDAL or dataset issue?
