[Freesurfer] Creating Labels

[Jahan, Bushra]

Hello,

I am wondering how to generate a label in FreeSurfer from peak activation in a 
cluster - is there a specific command?

Thank you.

[Freesurfer] Beta Extraction

[Jahan, Bushra]

When I ran the following command (with our data), I got the average beta values 
for each segmentation i.e. only 5 beta values (as opposed to 5 beta values for 
each subject).


mri_segstats --seg ocn.mgh --i beta.mgh --excludeid 0 --avgwf
beta.clusters.dat


That said, is it necessarily to run the previous command for each subject  (in 
order to extract 5 beta values for each subject) or is there way to extract 
betas for each subject from the group analysis?

Use something like
mri_segstats --seg ocn.mgh --i beta.mgh --excludeid 0 --avgwf
beta.clusters.dat

See mri_glmfit-sim --help for more info on the OCN file and mri_segstats
--help for info on the avgwf file

[Freesurfer] Cortical & subcortical cluster size

[Jahan, Bushra]

Hi,


I'm wondering which column in the FreeSurfer summary file represents the 
cluster size for the cortical and subcortical clusters.

[Freesurfer] Beta extraction

[Jahan, Bushra]

I am wondering how to extract beta values from the clusters of task functional 
data, particularly output of the multiple comparisons correction?
