Hello FreeSurfer Experts,
I'm following the longitudinal FreeSurfer tutorial using v5.1 to become acquainted with stream prior to analyzing our own data. I was able to follow the QDEC tutorial using this version on the Buckner data, however, I kept getting error messages in the QDEC when using the longitudinal data. I created the cross-sectional .dat file using:
long_qdec_table --qdec ./qdec/long.qdec.table.dat --cross --out ./qdec/cross.qdec.table.dat
The longitudinal measures (i.e. long.thickness-avg) did not appear in the QDEC, and I've tried to look at thickness alone, and got an error message after hitting 'Analyze'. I assumed these issues were arising due to the fact I downloaded the tutorial dataset for v6, when FreeSurfer v5.1 was installed.
I then tried to download the datasets for versions 5.1/5.3, but the files seem to be missing. Can these links be updated?
