Hi, Mark. Though FSL4.1.4 has one invwarp in /fsl/bin file ,i.e "invwarp", FSL4.1.5 has two invwarp , i.e "invwarp" and "invwarp_exe". When I exchanged "invwarp" for "invwarp_exe" in tbss_deproject(FSL4.1.5) as below, tbss_deproject was executed without trouble. You might understand this difference. ** tbss_deproject(FSL4.1.5) ** ...... for g in $list ; do echo "processing ${g}:" nextvol=`$FSLDIR/bin/imglob ../stats/${IN}_to_all_FA_tmp0* | awk '{print $1}'` warp=${g}_to_${target}_warp if [ `$FSLDIR/bin/imtest ${warp}_inv` = 0 ] ; then # $FSLDIR/bin/invwarp -w $warp -o ${warp}_inv -r $g $FSLDIR/bin/invwarp_exe -w $warp -o ${warp}_inv -r $g fi ...... I hope this is useful. kenji On Mon, 8 Feb 2010 21:33:43 +0000, Mark Jenkinson <[log in to unmask]> wrote: >Hi, > >We are unaware of any unresolved bugs with invwarp and tbss. >Can you please be more specific about what happens? > >All the best, > Mark > > >On 8 Feb 2010, at 19:04, Kenji wrote: > >> Hi FSL experts, >> >> I have recently discovered a bug in the "tbss_deproject grot 2" in >> FSL 4.1.5. >> I think this error might be due to a bug in the invwarp script. >> >> When I use the invwarp in FSL4.1.4 instead of it in FSL4.1.5, >> I could execute "tbss_deproject grot 2" in FSL4.1.5. >> >> Maybe, has the bug already been corrected ? >> >> Kenji >>
