[GRASS-dev] Forestfrag WARNING: ZSTD compression error -14: Unsupported frame parameter

Hi Václav / devs

···

I am running r.forestfrag in Windows 10, grass 7.6.2 Computation with a moving window size of 21 (but at another computer same happens at size 9) gives met the following error:

Some computations happened, but then something went wrong.

Something wrong with the libraries or the files (perhaps not enough space on disk?).

Probably, g.remove trying to clean something as the the script is exiting. Likely harmless.

Here, it is g.message failing, so at this point nothing works.

Too many open files? Or maybe just the error message happens to be too long.

Any idea what may be the problem here?

Try smaller region, smaller window. Look into task manager. …

Best,
Vaclav

It goes wrong when with the moving window computation using r.mapcalc. But when (e.g., with what moving window size) differs depending on the computer and the size of the raster.

I guess something with the files, as it works with smaller moving windows and it works in Linux.

Ah, ok

I did try a smaller region, this does seem to make a difference. I will try if I can do this more systematically.

This is probably a read error: data are not correctly read from disk. But this should be reported as a read error.

A ZSTD compression error has been reported previously when a raster map was compressed with ZSTD 1.3.x and on another system decompressed with ZSTD 1.3.y. Not sure if this applies here as well.
