Hi David,
there is no need to worry. Whenever we change the pipeline, there will be
consistent differences. Since we do not have ground truth thickness it is
unclear which method is “more right”. A comparison between cross and long does
not make sense here with respect to absolute values. It

Hello,
Our lab has been running a set of data from a pre/post-treatment study through
the FreeSurfer v6 pipeline. I was comparing the pre-treatment structural values
initially run through the cross-sectional pipeline with the same pre-treatment
data
Hi Melanie,
whenever you change anything consistently in the processing pipeline
(extra steps) you can expect a consistent change in the results. The
longitudinal pipeline goes through many different steps than the
cross-sectional. E.g. for surfaces, they get initialized from the
subject
Dear list and especially Martin,
we have used Freesurfers crosssectional as well as the longitudinal stream
and are inspecting the outcomes at the moment.
We have as quality assurance been inspecting regions where the
difference between initial CROSS results and the corresponding LONG
