Hi,
I am trying to segment cerebellum using FIRST on small group of subjects that
consists of adults and children. I am really impressed by the segmentation that
I get on adults, but the segmentation on children images are underestimating
the cerebellum by about 5 mm towards the bottom and sides.
I was wondering if there are any parameters I can adjust, or different models
that are available for children.
I am using the following commands to get the segmentation. (I believe
somebody has posted these here a few months ago, thanks :) ). "T1" refers to
an MPRAGE sequence, it is *not* brain stripped.
Thanks in advance for any input you can provide.
Deniz.
run_first_all -i T1.nii.gz -o T1_out
first_flirt T1 T1_to_std_sub -cort
run_first -i T1 -t T1_to_std_sub_cort.mat -n 40 -o T1_R_Cereb -m
${FSLDIR}/data/first/models_336_bin/intref_puta/R_Cereb.bmv -intref

first_boundary_corr -s T1_R_Cereb -i T1 -b fast -o T1_R_Cereb_corrected
