Hello List

Here is a summary of the question that I put out last week

Original Question:

It seems that there are two ways to go about this.  If you are
interested in getting a list of the cells or cell locations, then
r.stats will give you that.  You still may be left with the task of
sorting the cells to place them in a proper sequence.

However, r.thin + r.line will give you a vector of the path, and the
ascii output from that will give you the locations in the order which
they're crossed.

Thanks to Conn Copas, Simon Cox, and Rod Paterson for their prompt
