Hi Barbara - If you take out the "set baselist" part, you'll run the
cross-sectional TRACULA stream, i.e., analyze each time point independently. So
you want to leave that in to use the longitudinal TRACULA stream.
The base template itself (i.e., the median of the T1s of the time-points) may
not be used, but the files under the base template's directory are used.
Longitudinal TRACULA maps between the base space to the space of each DWI time
point, as described in the paper.
Can you please attach the file scripts/trac-all.local-copy? Since there's no
official 6.0 version yet but multiple beta versions of it, it's hard to know
which one you used.
Thanks,
a.y

Subject: [Freesurfer] longitudinal tracula error
Dear FreeSurfer experts,
I’m running tracula on longitudinal data but I’ve encountered the following
error at the “trac-all -prep” stage: ERROR: flag ; unrecognized (see below)
trac-preproc -c /Documents/TRACULA/TEST/S0001.01_T1/scripts/dmrirc.local -log
/Documents/TRACULA/TEST/S0001.01_T1/scripts/trac-all.log -cmd
/Documents/TRACULA/TEST/S0001.01_T1/scripts/trac-all.cmd ; trac-preproc -c
/Documents/TRACULA/TEST/S0001.01_T2/scripts/dmrirc.local -log
/Documents/TRACULA/TEST/S0001.01_T2/scripts/trac-all.log -cmd
/Documents/TRACULA/TEST/S0001.01_T2/scripts/trac-all.cmd ; trac-preproc -c

/Documents/TRACULA/TEST/S0001.01/scripts/trac-all.log -cmd
/Documents/TRACULA/TEST/S0001.01/scripts/trac-all.cmd ;
ERROR: flag ; unrecognized
As an example, I defined the parameters in my dmrirc file as:
set subjlist = ( S0001.01_T1 \
S0001.01_T2 \
S0004.00_T1 \
S0004.00_T2 )
set baselist = ( S0001.01 \
S0001.01 \
S0004.00 \
S0004.00 )
set dcmlist = ( S0001.01_T1/DTI.nii \
S0001.01_T2/DTI.nii \
S0004.00_T1/DTI.nii \
S0004.00_T2/DTI.nii )

My tracula directory contains 3 directories per participant: 2 with the
*.long.* output for timepoint 1 and 2, and a directory with the base. Including
the base gives the error above, but if I take it out, it asks for it: ERROR:
cannot find /Documents/TRACULA/TEST/S0001.01

>Maybe I am understanding this incorrectly?
Since the base is used to create the longitudinal output (*long*), including
the aparc+aseg.mgz file, and those are then used in tracula, I thought I could
run things without it. I decided to take out the “set baselist” part from the
configuration file — this way it seems to run fine (so far). But I assume it’s
there for a reason so I’m not sure this is a solution at all...
Any help would be much appreciated!
