I'm not sure what you mean by "inflate" here. Do you just mean to run
recon-all? Usually, you would run recon-all, then run segmentHA, then
register the fMRI to the anatomical (bbregister), then map the segs to
the fMRI space (mri_label2vol), then run something like mri_segstats
--seg segs-in-fmri.mgz --ctab ctab-for-HA --excludeid 0 --avgwf
ha-avgwf.dat --i fMRI.nii.gz
the ha-avgwf.dat will have a column for each seg in the ctab (excluding 0)

Hi developers!
I am running connectivity analyses for amygdala subregions using
images from a 7T scanner. I am wanting to transform the amygdala
segmentations into fMRI space (1.6 iso voxel) for individual analyses
and am looking for the best way to do this. Would it make sense to:
1. Inflate the norm.mgz brain, then run the segmentHA_T1.sh script,
and /then/ extract the individual segments.
2. Run the segmentHA_T1.sh script as usual, but inflate the rawavg
brain. Then, warp the full segmentation to fit the rawavg space
(using mri_convert -input <original_amygdala_segment> -at -rt
nearest -reference <inflated_rawavg_brain> -output
<inflated_amygdala_segment>), and /then/ extract the individual
segments.
Does it matter which way I do it? Is there another way to do it that
would be better?
Many thanks,
Elizabeth
