Hi - you may find that running fslreorient2std on your images beforehand will help.

Hi All,
I am new to FSL so forgive me if this is a simple issue. I am trying to run FSL FIRST on a data set of MPRAGES and I am having some problems with the registration of some of the images, they are zoomed and rotated relative to the template brain. This occurs in 15/27 subjects. I am running FIRST according to the pipeline on your WIKI pages, the results are the same whether I use run_first_all or first_flirt.
Any help would be much appreciated!
Best Wishes,
Alex
