Issue with rms values for greenspline -Cn20+c+i

Q&A
1

I remade the animation 5 but with this command

gmt greenspline geo.txt -Sc -Cn20+c+i -Ggeo.grd -Z2 -Emisfit.txt

This is the misfit.txt file. I notice that all the records have the same rms value (752.198173843). In the animation I see that the values are changing. Is this a bug?

Looking at it now.

For the record, fixed by https://github.com/GenericMappingTools/gmt/pull/8109.

BTW, @pwessel is it possible to select the range of grids that will be created?

I am thinking on something like this to only see from the 100th grid to the end.

gmt greenspline geo.txt -Sc -Cn100/"max"+c+i -Ggeo.grd -Z2 -Emisfit.txt
