Error during WMH segmentation in HyperMapp3r

Dear experts,

First of all, thank you for this tool and making your pre-trained models publicly available. I tried to conduct the WMH segmentation in one subject using a T1w and a FLAIR image of one subject using the HyperMapp3r GUI. However, I received the following warnings and errors.

Could you help me to solve this issue?.

Thank you very much in advance.
