T2 mapping error

Operating system: Win 10
Slicer version: 4.13.0

Hello developers,
I am trying to use T2 mapping module for knee cartilage. After choosing input volume and T2 output volume, I click apply and it gives this error message in Python Interactor:
module ‘string’ has no attribute ‘split’
I think that it may be related with incompatibility of the T2 mapping code with Python version (3.6.7) of the latest Slicer version.
Could you help me with this problem?
Thanks

You are right, that extension probably hasn’t been updated to the lates python. That’s usually not hard to fix, so maybe you can file an issue and or propose a fix to the developer.
