fsl_prepare_fieldmap is an unmodified FSL script that is called by the HCP 
Pipelines.  I would ask on the FSL mailing list about that.  You could try 
testing that script outside of the HCP Pipelines by using these commands line 
on the files:

${FSLDIR}/bin/fslmaths ${MagnitudeInputName} -Tmean ${WD}/Magnitude
${FSLDIR}/bin/bet ${WD}/Magnitude ${WD}/Magnitude_brain -f 0.35 -m #Brain 
extract the magnitude image
${FSLDIR}/bin/imcp ${PhaseInputName} ${WD}/Phase
${FSLDIR}/bin/fsl_prepare_fieldmap SIEMENS ${WD}/Phase ${WD}/Magnitude_brain 
${WD}/FieldMap ${DeltaTE}

Peace,

Matt.

Subject: [HCP-Users] Error during Field Map Preprocessing and Gradient 
Unwarping in the Functional Volume Pipeline

Hello,

I encountered a weird error while trying to run the FunVol Pipeline. After the 
motion correction is done I get this:

This looks very confusing, do you have any idea why is it so? At first I 
thought fsl 5.0.9 might be the problem, but even with 5.0.6 the problem 
persists. Also in the /tmp/ folder there are the files it can't open. I am 
using DistortionCorrection="SiemensFieldMap" and the only fields which are not 
set to "NONE" are Magnitude and Phase input names, Task and Phase encoding 
list, DeltaTE and final resolution.

Thanks so much in advance!

Vanessa
