Dear Christian Gaser and dear SPM - users,
following up on Elisabeths Email I am also interested in the modification of the longitudinal preprocessing script.
Specifically I am currently working on the implementation of a group-specific DARTEL template in the longitudinal segmentation.
My design includes two groups and two scans per subject before and after an intervention. Since I am expecting structural changes following an intervention, I built the template from the baseline images.
Am I right in assuming that the longitudinal segmentation realigns all scans from one subject to the mean image?
My question is now whether this can be altered (realign to baseline image) in order to fit the DARTEL template?
Do you think this approach makes sense at all?
Thanks a lot in advance!
Kind regards,
Marie.

Subject: [SPM] m0 files for longitudinal data processing pipeline in CAT12
Dear Christian, dear SPM users,
I have a question regarding the expert user settings for the longitudinal version of the CAT12 toolbox.
Is it possible (or easy to implement) to change the settings for the modulation step in the preprocessing pipeline to "non-linear only"?
I found out that this is possible in the "non-longitudinal" segment data batch using the expert mode but I have not found a similar line using the longitudinal toolbox batch.
I was also trying to copy the line of interest in my lngtd job file (matlabbatch{1}.spm.tools.cat.estwrite.output.GM.mod = 2;), however, this doesn´t seem to work!
Thanks a lot in advance for your help!
Elisabeth
