Hello everyone,  
I’m trying to use VMTK to create a model of some blood vessel from an MRI study but even though I’ve seen and tested with all the tutorials that I found I still do not get anything.  
Does anyone know what I’m doing wrong? I leave you a capture.  
Thank you very much! [https://gyazo.com/7ddd092ed47580b2e0871fdae818e8b1](https://gyazo.com/7ddd092ed47580b2e0871fdae818e8b1)

What do you do exactly? What do you expect to happen? What happens instead?
