Dear R Gurus,
I have an Albers project within Grass, and anoter in LatLong WGS84.
I want to import the Albers data within the LatLong WGS84 mapset.
But when I try r.proj (see below) I get ERRO:Error seeking on segment file
Any tip are welcome

50750 * 62835 cells corresponds to a temporary file size of ~12 GB,
which requires large file support (LFS). I don't think that this works
on Windows at present, in which case you'll need to down-sample the
input file first.
(Raster maps are normally compressed, so the actual input file could
be under the 2GiB limit, but the temporary file required by r.proj
isn't compressed, as it needs random access).

Hi Glynn,
Thanks for the reply. I will resample the largest one.
