Hi Doug,
Sorry to bother again and I hope I'm not becoming too annoying with my
questions. I will be very grateful if you can advise what to do for the
following:
1) I am still struggling to find a way to localize my clusters in other words
to get the nearest cortical label(annotation) if I know the MNI coordinates on
the MNI space.
As a reminder I was trying to get a the nearest cortical label(annotation) on
the CVS space since this data was registered on the CVS space but can I get
their
location on the MNI space if I have
their coordinates without doing another registration to MNI? Can I use
fsaverage or what should I do?
2) Can you please advise me what is the best way in catching the uncorrected
clusters results from the sig.mgh for a structural study:
Should I use the:
mri_glmfit-sim \
--glmdir lh.GroupAnalysis_Thickness_15.glmdir \
--cache 2 pos \
--cwpvalthresh .99 \
--overwrite
But in this case I am not getting all the clusters regarding their significance
after correction by multiple comparison? I don't want the clusters from
multiple comparisons just the uncorrected one.
3) For a paper to be published what is the recommended threshold (what people
use in general) for the voxel-wise threshold of the clusters when running the
perm or grf. Is a threshold of 3 acceptable (P<0.001) or in general I should
use 2 (p<0.01)?
Many thanks.
AK
