<br>
I’m using the 3D-Forest-Fragementation Modul developed by Vaclav and <br>
have produced a workflow for the calculation. It is working well and <br>
I’m getting plausible results. While applying this workflow for my <br>
whole study region (35 plots/regions) it only works for about 50 % of <br>
the plots. The others fail at the step where I use <br>
r3.count.categories. I can’t see the link respectively the difference <br>
for this error. That’s why am asking for a hint:<br>
<br>
I’m running Grass 7.8.2 (64 bit), Python 3.7.0, wxPython 4.0.7 on Windows 10<br>
<br>
The problem occurs while running this command:<br>
<br>
"r3.count.categories input=ff_mean_131_2 output=ff_mean_131_2_count <br>
slices=ff_mean_131_2_slice --overwrite"<br>
<br>
With this error:<br>
<br>
"[…]<br>
Raster map 22 Filename: ff_mean_131_2_slice_00022<br>

<br>
For each failing plot the error occurs in this step. The slices seem <br>
to be generated correctly. I couldn’t see differences while displaying <br>
them or comparing the raster metadata.<br>
In the different plot its always another slice (2D Raster) and another <br>
row where the uncompressing fails. I tried to reduce the plot-size and <br>
found out, that the error occurs always in the same row of a plot. If <br>
this row is excluded, it works fine.<br>
That’s why I think it has nothing to do with missing space on disk, or <br>
not enough calculating capacity.<br>
Has someone an idea what’s the problem? Thanks very much!<br>
<br>
Greetings,<br>
Olivier<br>
