Dear All,
I have run into problems with a longitudinal analysis using v5.0.0 (freesurfer-Linux-centos4_x86_64-stable-pub-v5.0.0) that seemed to work fine under v4.5.0. For both analyses I processed the raw data from scratch since they were run on different clusters.
Following the instructions at http://surfer.nmr.mgh.harvard.edu/fswiki/LongitudinalProcessing I initially processed all images using the cross sectional stream, eg
recon-all -s PATIENT016_TIMEPOINT1 -i PATIENT016_TIMEPOINT1 then created a template from all time points for each subject, eg recon-all -base PATIENT016 -tp PATIENT016_TIMEPOINT1 -tp PATIENT016_TIMEPOINT2 -tp PATIENT016_TIMEPOINT3 -all Finally I tried to run the longitudinal processing stream, eg recon-all -long PATIENT016_TIMEPOINT1 PATIENT016 -all
where I ran into the following error message
"ERROR: longitudinal base ID cannot be the same as a timepoint subject ID (in /home/asimmons/images/FREESURFER/PATIENT016/base-tps) Find more info at: http://surfer.nmr.mgh.harvard.edu/fswiki/LongitudinalProcessing"
The longitudinal base ID is however not the same as any of the timepoints in /home/asimmons/images/FREESURFER/LNDMCI016/base-tps which just contains a list of the time points as expected -
PATIENT016_TIMEPOINT1 PATIENT016_TIMEPOINT2 PATIENT016_TIMEPOINT3
Best wishes,
Andy Simmons
