Hi All,
I'm trying to run fslvbm on a collection of healthy controls, but there appears to be something strange happening at the second stage fslvbm2.
when I look at template_4D_GM there are a lot of subjects (31) that are completely blank, and when I look at the associated first segmentation images, the images are all ones.
I had a look at the the error output of fslvbm2a, which reveals the error 'MeaNsK variance nan' fslvbm2b produces the warning 'WARNING::in calculating COG, total = 0.0'
which suggests some kind of fault with the input data, but I can't see anything obviously wrong. step 1 completes okay, and the betted images look fine.
Any suggestions as to how to proceed would be welcome
Best Wishes,
Pete
