Hi I'm a SPM5 beginner and I've a problem with a multi-sessions test. I've 4 runs which are acquired with the same EPI parameters. I set the model specifications, introducing as multiple regressors the motrion correction parameters and when I try to run it this error compares: spm_check_orientation but my images are acquired in the same orientation! what is the problem? thank you Stella __________________________________________________ Do You Yahoo!?
