good day SPMers-

I'm extracting VOI eigenvariates and am concerned with the values of my % variance explained.
I'm getting values between ~ 40 - 70 %... at what point should I re-evaluate my coordinates and/or spherical radius?
Obviously this is an issue along a continuum, so I'm hoping to get more of a sense of what others in the field do if they encounter this.
Thanks so much.
