Hi Freesurfers!
Has any one got an answer to this query asked sometime ago:
Hi list,
I have a question, probably trivial, on OFFSET in qdec GUI. What's this? And
what I can do using it?
Hi Bruce,
I'm referring to offset in qdec/Display threshold line, near Min/Mid/Max. For
example, I'm
Hi Bruce,
Thanks for the information. The surface works for me. These histograms
generated from the surfaces, if I understand correctly, are based on the
intensities along the boundaries of one region. Can I also generate histograms
including the whole region? Like Pick putamen or caudate and
Hi Yue
tksurfer will only display cortical histograms. For subcortical regions
you are probably best off using something like matlab (which would be
pretty trivial)
cheers

I think the latest version of FSL has this sorted out (it doesn't change
your machine's POSIXLY_CORRECT setting except briefly in the middle of
fsl_sub).
Peace,
Matt.

Dear Freesurfers and experts
Can any one please tell me what the offset box next to the max. box (under
Threshold) in QDEC GUI is for? When I change from e.g 0 to 1 or higher I get
larger significant clusters. How and when is this feature used?
I also notice this very question is on the
Hi Bruce,
Thanks for responding so quickly.
Sorry I probably don't describe my question clearly and my examples are bad.
This is really new to me. So please correct me if I say something wrong. Let me
explain again. Hopefully it will make some sense.
What I want to do is first to segment out
Hi Bruce,
Thanks. Is it statistically sound to use e.g offset 1? My between-group
results are not FDR corrected at offset 0, but if I change the offset to 1
results will be larger in size and FDR corrected! Any pitfalls with that?
Cheers

Got you. I will check out ribbon and read more about mri_vol2surf. Thanks for
your help!

Hi Doug,
Thanks, this seems to work!
Quick question -- in the past we've done ROI analyses where we've
functionally constrained our labels. When calculating percent signal
change we would take the output from funcroi-table-sess divide it by the
output of funcroi-table-sess with no -c flag (the

Great, thanks for the clarification Doug!
Best,

It depends on how are you defining percent contrast. What you are are
slightly different methods.
Using -m cespct is equivalent to computing
100*Sum(contrast_i/baseline_i)/N where i is a voxel in the ROI
Your method is equivalent to
