Hi,
I am trying to perform the EPI distortion correction using FEAT, but I end up getting the following error:
child process exited abnormally
while executing
"fsl:exec "${FSLDIR}/bin/feat ${fsfroot}.fsf -D $FD -I $session -prestats" -b $prestatsTime -h $initID $jobHalt -N feat2_pre -l logs "
(procedure "fullFirstLevelAnalysis" line 169)

"if { $done_something == 0 } {
if { ! $fmri(inmelodic) } {
if { $fmri(level) == 1 } {
for { set session 1 } { $session <= $fmri(multiple..."
(file "/usr/local/fsl/bin/feat" line 388)
Any idea what is going wrong? These are the steps that i have followed:
1. I have two echo planar images with opposite phase encode directions (PA and AP) and I constructed the field maps following the tutorial from https://lcni.uoregon.edu/kb-articles/kb-0003
2. When I am setting up the FEAT, I have select the 4d data as my functional EPI series, the corresponding output dir, the fieldmap(in rad/sec), the brain extracted magnitude fieldmap, unwarp direction -y, corresponding TE and effective EPI echo spacing.
Any suggestions?
Thanks
