I've been using an FBIRN write up with great success for the last 5
years.
The trick is to convert the phase map into -Pi-0-Pi map. In the siemens
phase map dicom files these are encoded from 4096-0, with 2048 being the
zero in phase space.
Here is a script that tells you how to do it.

Subject: [FSL] Using Siemens Trio field maps in FUGUE
Hi,
I am writing to request help with using Siemens Trio field map in FUGUE.
There is a Siemens filed mapping protocol that provides two image files.
The
first looks like a field map image, while the second looks like a
magnitude
image. However, when I submit these files to FUGUE via the MELODIC gui
the
results are strange, (It appears as if the brain is on fire!).
I am encouraged by a report that something very similar has been done
(see:
http://users.fmrib.ox.ac.uk/~kylep/kyles_papers/abstracts/ismrm_def_abstract_submitted.pdf).
I would be grateful for any insights!
