v.support

[Brian Connelly]

Hello,

I have a problem when I am running v.support for
a vector file that I have imported using v.in.ascii.
There are two adjacent polygons in the file which share about
four points.  The coordinates in the attribute file definitely
fall within each polygon.  When I run v.support, I get the
error message

PNT_TO_AREA FAILED ...

for both polygons and attributes.  However, if I create two
separate ASCII vector files each with one polygon and one
attribute, I can successfully run v.in.ascii and v.support.
Has anyone had a similar experience or know why this is
happening?  The points that the polygons share are identically
the same in each polygon list.

Thank you,

Brian
