[Marsbar-users] Error message

[Dougherty, D. <DDOUGHERTY@PARTNERS.ORG>]

Hello fellow Marsbarers:

I am using the PET data extract function nin conjunction with a previously
defined and saved ROI. I can get extracted values using the GUI function, but
when I try to extract values from an SPM.mat file I get the following error
message. Checked permissions already and they're OK. Any thoughts?

MarsBar analysis function prepended to path
MarsBar defaults loaded from base defaults
