External Email - Use Caution Hi Doug,
I was looking at the dt_recon code and was wondering if it would be possible to incorporate a field map into the eddy_correct portion? I tried to test it on one subject and tried to add --field=$pathtofieldmap to the eddy_correct command however I got the following error. cd /Volumes/DANIEL/dti_freesurf/dtrecon/AES101.Ex./ectmp eddy_correct /Volumes/DANIEL/dti_freesurf/dtrecon/AES101.Ex./dwi.nii /Volumes/DANIEL/dti_freesurf/dtrecon/AES101.Ex./dwi-ec.nii 0 --field=/Volumes/DANIEL/AES101/AES101.Ex/FieldMap2dti_smoothed processing /Volumes/DANIEL/dti_freesurf/dtrecon/AES101.Ex./dwi-ec_tmp0000 Unrecognised interpolation method: --field=/Volumes/DANIEL/AES101/AES101.Ex/FieldMap2dti_smoothed processing /Volumes/DANIEL/dti_freesurf/dtrecon/AES101.Ex./dwi-ec_tmp0001 Unrecognised interpolation method: --field=/Volumes/DANIEL/AES101/AES101.Ex/FieldMap2dti_smoothed I probably did this in a silly way. I wonder if and how I could add a field map I created to the eddy_correct command in dt_recon. Below is what I tried to change.... set fec = $OutDir/dwi-ec.nii if($DoEddyCorrect) then echo "#@#-------------------------------" | tee -a $LF echo "Eddy/Motion Correct" | tee -a $LF date | tee -a $LF set ectmp = $OutDir/ectmp mkdir -p $ectmp pushd $ectmp > /dev/null set cmd = (eddy_correct $f $fec $ECRefTP *--field=/Volumes/DANIEL/AES101/AES101.Ex/FieldMap2dti_smoothed*) #set cmd = ($cmd; mri_convert ${fec:r} $fec) #set cmd = ($cmd; rm -f ${fec:r}) #set cmd = (cp $f $fec) echo "cd `pwd`" | tee -a $LF echo $cmd | tee -a $LF $cmd |& tee -a $LF if($status) exit 1; if(! -e $fec) then echo "ERROR: when running eddy_correct" | tee -a $LF exit 1; endif popd > /dev/null rm -r $ectmp echo "" | tee -a $LF echo "" | tee -a $LF else echo "#@#-------------------------------" | tee -a $LF echo "Skipping Eddy/Motion Correct" | tee -a $LF set fec = $f endif Thanks for any help you can provide, *Daniel Callow* *PhD Student, Neuroscience and Cognitive Science* Exercise for Brain Health Lab University of Maryland, College Park *ddcc2...@gmail.com <ddcc2...@gmail.com>* 443-254-6298
