Problem with fsl_prepare_fieldmap

Hello,

I have encountered a weird error message. It seems that something is wrong with fsl_prepare_fieldmap. I tested the following code line by line and it is only the last line that causes the crash.

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

When I run it the following appears:

(standard_in) 1: parse error

(standard_in) 1: parse error

Loading volumes

Rewrapping phase range to [-pi,pi]

Number of phase splits = 8

Calculating starting matrices (709 by 709)

Finished connection_matrices

Done. Created /Users/user/Desktop/FieldMap for use with FEAT.

Despite what it says it doesn’t really create /Fieldmap. Do you have any idea of what might be wrong here?

Thanks so much in advance!!
