Thanks very much, that is all working well. I did try the addon you
mention, but using grass7 it wont install in either linux or mac os

It's just a shell script, so you might be able to just download it and run it in a GRASS GIS session, unless the script uses specific grass6 features.


I'm having some trouble with the final layer though when trying to
sample a raster....


Using this command

v.what.rast map=TSELinesSplit500_w_lay2@PERMANENT type=centroid
raster=a250m_ATI@MojaveCovariates_250m column=RC1

WARNING: No record for category 0 in table <TSELinesSplit500_w_lay2>

Any idea why I have no category 0?

This actually sounds like you have a feature with category 0 (which AFAIK shouldn't happen, unless you ask for it explicitely), but that there is no entry for this feature in the attribute table.

You could run v.to.db op=cat to create entries in the table for any features that don't have one yet.
