Dear Chloe,
Thank you for your swift reply. Please find attached sample images of
the phase maps.
Some additional information I forgot to mention was that I am running
SPM8 on a Windows Vista x64 workstation. I have not yet gotten around to
installing the latest patch, as it was released in the middle of my
preprocessing pipeline.
Best wishes,
Haakon
