Hi All,

I am trying to run LesionToads on T1 SPGR and Flair for MS lesion segmentation, and when I click "Ok" it pops up with "Atlas File - No Lesion - T1 Only: Value None is invalid." Can any one please suggest where am I going wrong. I have not changed any default options. Am I suppose to provide any atlas related *.txt file under "Atlas Files" tab option?

Thanks,
Sneha
