Dear all,
I am working with a raster with very large integers. That are stored as 64 bit
floats (imported from a GTiff). I wish to extract part of these values with an
integer division. The first approach was:
r.mapcalc 'short_ints = int(long_ints)/100'
However, this results in something
Hi Job,
looks like something is going wrong creating the attribute table for the
interpolation points vector. This is made with v.db.connect at the time of the

SQLite default? I would ask you to verify whether

Dear all,
I am trying to transform a polygon layer to lines with a command like:

Hi Stefan, thank you for the reply.
The outputs you request are below. v.rast.stats takes about 8 GB of RAM before
failing, only 1/4 of what is available in the workstation. I also tried
increasing the memory parameter but it never goes above 8 GB and fails all the
same.
Let me know if there
Thank you all for various replies. Some reactions:
1. The workstation has 32 GB of RAM and 12 CPU. What is the expected RAM
requirements for v.rast.stats?
2. v.to.rast also fails, see below.
3. What would be the way to check the health of the vector? The table in
Postgres at least is fully

Dear all,
I am getting the error "Unable to seek" with v.stats.error. There is not much
information that could point the cause, just a warning saying that some data
base files are not found. I checked the database connection and everything
looks in order (see below). Any hints on what may be

Thank you both for your patience. The issue was indeed a wrong target path.

Hi again Markus, thank you for following up.
In your example we can see this:
rm /home/mneteler/tmp//grass76/include/Make/Platform.make

How can it work? Is the file recreated somehow after the rm command? What

I am compiling GRASS 7.6 in an HPC cluster running Scientific Linux. make is

This is the configuration command:

have changed since. Can anyone shed some light on modern requirements?
