Hi Fernando - Thanks for uploading your data. Looking at the primary
directions from tensor fit on the data that you sent me (see screenshot),
they seem to be off by a 90 degree angle from what you'd expect them. This
means that your gradient table is probably off as well.
Hope this helps,
a.y

Dear Freesurfer/Tracula users,
Finally I could successfully test Tracula and I think it is amazing what it can
do automatically. These are the commands I used:
export FREESURFER_HOME=${HOME}/Programs/freesurfer_510 && source
$FREESURFER_HOME/SetUpFreeSurfer.sh
source /etc/fsl/fsl.sh
export FSLPARALLEL=condor
trac-all -prep -c
/home/labneuroimg/STATION_FLENI/Tensores/Fernando_Ventrice/dmrirc_Fernando_Ventrice
trac-all -bedp -c
/home/labneuroimg/STATION_FLENI/Tensores/Fernando_Ventrice/dmrirc_Fernando_Ventrice
# "trac-all -bedp" gave some errors so I used bedpostx directly:
bedpostx

trac-all -path -c

All finished without errors, but there seems to be a problem with CC Forceps
Mayor volume, which gave very small values. Is this OK or I made some mistake?
First I tested with some patient and other fiber tracks also gave very small
volumes. I attached some pictures and the dmrirc and trac-all log files.
Best,
Fernando Ventrice
