Incorrect Folder of topup for fsl/6.0.7.7

[yangliu2009]

Software fsl/6.0.7.7 appears to havesrc/fsl-topup/ instead of src/topup. But freesurfer (trac-prepro and nifti1.py) still uses the folder src/topup.

/bin/trac-preproc:  if ($dob0 > 1) then			# B0 inhomogeneities: with topup
/bin/trac-preproc:      echo "ERROR: Cannot correct B0 distortions with topup" |& tee -a $LF
/bin/trac-preproc:    # If image has an odd dimension, must turn off topup subsampling :/
t/bin/trac-preproc:    set cnf = $FSLDIR/src/topup/flirtsch/b02b0.cnf
/bin/trac-preproc:      set cmd = (cp -p $FSLDIR/src/topup/flirtsch/b02b0.cnf $dwidir)
/bin/trac-preproc:    set cmd = topup
/bin/trac-preproc:    set cmd = ($cmd --out=$dwidir/topup)
/bin/trac-preproc:    set cmd = ($cmd --iout=$dwidir/lowb_topup.nii.gz)
/bin/trac-preproc:        set cmd = applytopup
/bin/trac-preproc:        set cmd = ($cmd --topup=$dwidir/topup)
/bin/trac-preproc:  else					# No topup, only combine runs
/bin/trac-preproc:    if ($dob0 > 1) then			# Have b=0 images unwarped by topup
/bin/trac-preproc:      set lowbase = $dwidir/lowb_topup
/bin/trac-preproc:    if ($dob0 > 1) then			# Use previously run topup output
/bin/trac-preproc:      set cmd = ($cmd --topup=$dwidir/topup)
/bin/trac-preproc:    if ($dob0 > 1) then			# Apply unwarping from topup
/bin/trac-preproc:        set cmd = applytopup
/bin/trac-preproc:        set cmd = ($cmd --topup=$dwidir/topup)

Can fsl change the folder topup to fsl-topup?
