Hi,

running Conn 18.b
Same issue as above.
three groups, first group has 4 sessions, second two groups have 2 sessions each. When I run ALFF or fALFF, only the first group get results, the other two groups get all zeros.

Other voxelvise constant work fine

First time I ran setup, I forgot to indicate "allow missing data", but fixed that since, and reran setup with the overwrite option, but the fALFF and ALFF error remains

thanks
Clas
