Neper version: 4.10.1
Module: -S (post-processing)
Command: neper -S n2d.sim -rescell gos
Platform: Ubuntu (WSL2)

When computing GOS from a raster tessellation (.tesr) using Neper 4.10.1 following the EBSD tutorial:

https://neper.info/doc/tutorials/ebsd_process.html

the computed GOS values are orders of magnitude larger than those shown in the tutorial.

Tutorial expected values:

3.124415538011
2.405535676705

My computed values:

36.211881332051
44.493304803758

Create raster tessellation following tutorial (EBSD → TESR)

Run

neper -S n2d.sim -rescell ori

(Expected output, OK)

Run

neper -S n2d.sim -rescell gos

inspect:

more n2d.sim/results/cells/gos/gos.step0

output is ~10× larger than tutorial values.
