Related to ticket #1038 - Running the following:

r.statistics --verbose base=HUC@PERMANENT cover=ag@PERMANENT method=sum
output=huc_ag

results in the following error:

Access is denied.
ERROR: o_sum: running r.stats command

Same results when attempting to run an average as well. The fix mentioned
in the other ticket (change security settings to full control for USER)
didn't work.

Comment:

does r.stats run on its own? how about `g.tempfile pid=1234`?

note o_sum.c in gr65 calls r.stats via system() with:

{{{
#define STATS "r.stats"
#define RECLASS "r.reclass"
...
     sprintf(command, "%s -cn input=\"%s,%s\" fs=space > %s", STATS,
basemap,
             covermap, tempfile1);

     if (stat = system(command)) {
         unlink(tempfile1);
         G_fatal_error(_("%s: running %s command"), me, STATS);
     }
}}}

but before dealing with system(), a starting point might be:
{{{
Index: o_sum.c

--- o_sum.c (revision 42566)
+++ o_sum.c (working copy)
@@ -27,7 +27,7 @@
      tempfile1 = G_tempfile();
      tempfile2 = G_tempfile();

- sprintf(command, "%s -cn input=\"%s,%s\" fs=space > \"%s\"", STATS,
basemap,
+ sprintf(command, "%s -cn input=\"%s,%s\" fs=space output=\"%s\"",
STATS, basemap,
             covermap, tempfile1);

      if (stat = system(command)) {
}}}

Comment(by nkale):

Didn't really follow anything below "note 0_sum.c in gr65...", but as for
the commands you suggested:

r.stats ag@PERMANENT - runs fine, no errors, meaningful output
r.stats HUC@PERMANENT - runs fine, no errors, meaningful output
g.tempfile pid=1234 - no errors, output is:
{{{
C:/Users/Nat Kale/Documents/Grass_GIS
DataBase/Alberts_Landcover/PERMANENT/.tmp/1234.1
}}}
That is the correct location & mapset. Can't think of anything else to
try.

Comment(by hamish):

could you give the grass 7 daily snapshot a try? it uses an improved
method to generate the stats and hopefully bypasses the problem.

system() replaced with G_system() in grass 6.5svn with r42570, daily
WinGrass snapshots for 6.5 are probably broken until bug #1089 gets fixed,
and it this wants testing there before backporting to 6.4.

cheers,
Hamish

That worked. Ran with a slightly smaller dataset (didn't know if the
raster format was the same between 6 & 7, so I had to do some lengthy re-
importing), but I didn't get any errors, and the output map made sense.

On the other hand, in 7 I can no longer launch GRASS in MSYS mode, but
that's maybe a bug for another ticket.

Thanks,

Nat

ok, good. in a few days once grass6.5 daily snapshots are fixed I might
ask you to try that.

for now it is the same, but that is likely to change in the future.

Known problem, being worked on.

I've tried following grass65-nightly build:
WinGRASS-6.5.SVN-r42351-1-Setup.exe

{{{
(Sat Jun 19 13:28:32 2010)
r.statistics base=elevation_int@user1 cover=geology_30m@PERMANENT
method=sum output=elev_int_geol
(Sat Jun 19 13:28:33 2010) Befehl ausgeführt (1 sec)
}}}

r.statistics seems to work, no error message.

the nightly build is from 2010/06/19, maybe revision-number is not
correct?
tested on WinVista32

right, grass65 is broken for several days. Fixed, going to recompile all
branches. Martin
