I have a data set of a right-handed task, using a standard protocol which
gives activation maps which are bilateral, but predominantly ipsilateral M1
and S1. I have used MRIconvert to convert the data to analyse format, but
checked with avworient that the data is still radiological. I have used FSL
3.2 for the full data set, but checked samples on FSL 3.3, still with
strongly ipsilateral activation. I've checked the protocol with a healthy
volunteer - on FSL we still have predominantly ipsilateral activation, which
is contralateral when we use a different software package.
Is there some point within FSL that the data could have been flipped? If so,
is it possible to identify and rectify the problem?
