Error: Expression `size:rel' could not be processed

[necdetaliozdur]

Hello,

According to the documentation, it is possible to obtain average values of statistical values by appending :rel to the keyword. I'm trying to find the average sizes of all cells with the key size:rel since my domain is very small, thus the absolute sizes come out very small as well. However, when I try to use this feature, I receive an Expression 'size:rel' could not be processed error. I think I am using the correct command and syntax according to the documentation. I also tried putting quotes around the expression, but the issue persists. Here are the details of my system and the command I used:

Neper Version: 4.10.1
Operating System: Fedora 41
Command:

neper -T -dim 2 -n 8 -domain "square(30e-6,15e-6)" -crysym hexagonal -ori "fiber(0,0,1,0,1,0):normal(theta=20)" -oridescriptor euler-bunge -periodicity 0 -morpho "diameq:lognormal(1,0.15),1-sphericity:lognormal(0.145,0.03)" -regularization 1 -o gage-2d-08 -format tess,geo -statcell size:rel

Terminal Output:

I would greatly appreciate any help regarding this issue. Thank you for your assistance!
