Hi,
I have some troubles with the parameterization step. I've imported my data, used the "In-house Topology Fix", checked visually the resulting xxx_fix.mat (see attached) and everything looks ok. Hoever, when I run the next step (parameterization), i have the following message in Matlab:
 
ParamCALD

I have the same message when I tried with the example data.... Thank you for your help
