A value error when using morphman-area

[JIsaacW]

Hi, I'm new in morphman, When I use morphman-area command to adjust a coronary geometry model, there is an error like this:

Please select region of interest in the render window.
Quit renderer
-- The chosen region points: [-3.548530340194702, 1.9141699075698853, -15.790369987487793]

ValueError: Error on input data

This is my input:

morphman-area -i model.vtp -o symmetry_stenosis.vtp -b 250 250 250 -m stenosis -r manual --size 2.0 -p 50

How can I solve this error, thanks!

Hi @JIsaacW,

Thanks for reporting this issue. Seems to be an issue when splining the centerline, so perhaps it is related to the input centerline.

Could you possibly share the geometry you are using for manipulation?

Best regard, Henrik
