[Marsbar-users] error during estimation

[Mayuresh K. <may...@gm...>]

Hi Matthew,

I was wondering if you know why I would be getting this error. I get the
error while using the 'Results->estimate results' option from the GUI. The
error is seen only for a particular subject while using an anatomical ROI
mask from an atlas.
