Example "05A_Regions_vs_Gradients" can not run

Question

When I enter "./run.py --visualize" in the terminal try to run this example, I got the following error message.

The meshalyzer displays "2021-07-28 DeltaAPD_0.10-2.00.dat

Points number mismatch: Expected 10201 or 20000 but got 10200

" and meshalyzer shows an orange screen, and this file has 10201 lines.

The terminal displays "ERROR: : SHADER: VERTEX:: COMPILATION FAILED

0:14(10): error: gl_Position' redeclared

ERROR: : SHADER: : PROGRAM: : LINKING FAILED

error: linkinq with uncompiled/unspecialized shader"

Thank you!

I tried to reproduce your error but couldn't using the current version of openCARP in the master branch and the linked version of carputils and the experiments in openCARP/external.

Please provide more information on your installation (package or source installation, version, operating system).

Thank you very much for your reply! This problem was solved after I reinstalled meshalyzer. I guess I had some problems when I first installed meshalyzer. If I find the answer in the future, I will report it here to help more people.
