[GRASSLIST:5329] Re: r3.out.v5d error

[Christoph Hoesli]

Thanks a lot for your help. The v5d export works with the latest
CVS-repository
code.

I still had the same error with files containing less than 800 rows. So I
checked out the latest code for the g3d module from cvs. Now it works! The
handicap
is a limitation of 400 instead of 800 rows.
I am able to export g3d files to v5d format without an error. (files with
less or
equal 400 rows)

Christoph,

That's the reverse of my problem!  I've been having problems with s.vol.rst
which I have not solved yet.

You almost certainly should use the g3d routines from the latest CVS
version of 5.0 source.  (Not to be confused with 5.1)  Quite a few
important fixes have been done there.  Alfonso Vitti has done a number of
fixes - including some critical ones to get the g3d read and write
functions behaving properly.  Some of the loops in the various utilities
are still causing reversal in N-S or depth.  I've been working with the v5d
output over the last 6 weeks using 3d geophysical models of electrical
properties of the sub-surface.  I've modified the loops in s.vol.idw and
r3.out.v5d to store data in the correct order and thus display in vis5d
right way up and oriented N-S correctly.  I believe those recent fixes went
into the CVS.

Looking at the source briefly I note that it might try to use 801 rows in
vis5d for 800 rows of data.  (Although the test printing the error message
should not have failed on equality???)  I looked at the new code, so its
also possible that Alfonso Vitti has fixed the problem (he moved where the
row/cols are read form region).

Why not try dropping a few more rows to see if the problem goes
away.  Please let me now the outcome.

Cheers,
John Harrop
