Hi All,
I have created two ROIs from first time point Qdec group comparison. I need
to use this ROI labels to extract the thickness from tp1 and tp2 registered
to base (template) subjects(from longitudinal pipeline).
Would you please let me how can I convert the label from 1st time point
space to
Hi Erik,
30 mins for a subject sounds correct. If the text files with the volumes are
there, and the segmentations look plausible, then everything should be fine.
One more thing: it the outputs are in specific directories, please note that we

Hi:
I want to do a longitudinal study between two time points of a patient... I

Hi Maia
that's surprising and a bit worrisome. It's been a while so I don't
remember the details of the differences between 5.1 and 5.3. Did you have
to edit the aseg in 5.1?
cheers

This appears to be a problem with the 5.3 version of freeview. I think
there is a way to get a newer version. Perhaps Zeke can point it out.

Hi Gonzalo,
yes, exactly, you only look at the *.long.* folders. Take a look at this
page:
http://surfer.nmr.mgh.harvard.edu/fswiki/LongitudinalStatistics
specifically if you have 2 time points for all subjects, you can use the
tools for analyzing slopes:

Hi,
We ran our subjects through version 5.1, did a thorough quality check and
troubleshoot the data, and then re-ran our subjects through version 5.3 to
verify that our findings were consistent between versions.
We're running into an issue where we are not able to replicate our

or global volume) in QDEC. As I said earlier,

Hi,
I have two groups and two time points (pre and post). I want to investigate
group*time interactions in an fMRI task taken at both time points.
I have run all the subjects through first level FEAT analyses in FSL as
well as the longitudinal Freesurfer pipeline.
I'm thinking of registering
Yes, it seems to be a qdec issue since mri_glmfit works by itself even without
demeaning the larger values of ICV. Thanks anyway.

Right, strictly speaking, permutationis for orthogonal design matrices
only, which is not the case when you have a covariate. There was a
recent paper by Anderson Winkler Permutation Inference for the General
Linear Model in NI in which he goes over various permutation methods

Oh, sorry, this is not a problem with mri_glmfit as I had thought. It is
a problem with qdec itself on your data. I'm not sure what to tell you
because I can't debug it without your data (and maybe not even then).
You can use mri_glmfit directly.
