Dear Freesurfers,

Can anyone please help me with mris_curvature_stats? Anyone was using or testing it and encountered the same parameter problem or errors?

Thanks and best Maria

Hello FreeSurfer developers,

I have three issues with mris_curvature_stats:

1. I attempted to compute curvature on a *noisy sphere* surface (attached) using different -a parameter values, integers from 0 to 10, like this:

mris_curvature_stats -a 5 -f surface -m -o noisy_sphere_r10_a5.stats -G --signedPrincipals --writeCurvatureFiles noisy_sphere noisy_sphere_r10

However, there is no slight difference between the curvatures in the output files. Also the runtimes do not vary. Am I calling the function wrong? Attached is also the ".stats" output in case it's of any use.

2. When running the same command as in 1. (without -a parameter) on a *noisy cylinder *surface (attached), I got the following standard output with errors:

3. When running the same command as in 1. (without -a parameter) on a *smooth cylinder* surface (attached), I got the following standard output with an error:

I've searched the list and no similar errors have been reported. Does anyone know why the errors happen? Can it be because the cylinder surfaces are open and have edges?
