Hi,
I have just been handed a file of old grass 4.1 mapsets and they want them
to be readable in Grass 6.4 for exporting to ArcGIS.
I have 6.4 on a linux computer, is there anyway of opening them in 6.4 or do
i need to install 4.1? Where do I find 4.1? is there an easy sudo install
grass4.1 commandline?
I tried to access them with 6.4 and i get the error Warning:<PERNAMENT> is
not a valid mapset.
Thankyou
Gary

Do you want to use raster or vector files? Or both?

Perhaps it is not needed to install GRASS 4 for this. I have started a new
Wiki page to help with the needed format migrations:

There may be subtle differences in the PROJ_INFO and/or DEFAULT_WIND files
which are ASCII and hence easy to update.
The "meld" tool (http://meld.sourceforge.net/) is very nice to compare two files
and to sync them.

6.4 should be able to handle raster maps from 4.3; I don't know
whether anything changed between 4.1 and 4.3. Vector data may be a
different matter; there were substantial changes to the vector code
between 5.3 and 6.0; if you have problems specifically with vector
data, try 5.4.1.

Is that a transcription error? It should be PERMANENT, not PERNAMENT.
The "is not a valid mapset" error normally indicates that the
directory lacks a WIND file. Copying the DEFAULT_WIND file (if it
exists) to WIND should suffice.
