Hi, sorry for the many months to get back to you. I have just updated
the documentation on https://surfer.nmr.mgh.harvard.edu/fswiki/PetSurfer
to indicate how to use your own segmentations. I'm assuming that you
have a volume with choroid plexus labeled that you want to merge into
the stream. Take a look and see if that does what you want.

Hi
I am reaching out to ask some questions about PetSurfer. I am working
with an open access dataset (ADNIDOD

to analyze neurobiological differences in veterans with a history of
TBI. I am hoping to use the PET data (there are the raw dicoms and
preprocessed PET data) to segment the choroid plexus using aspecific
segmentation software.

have already done the segmentation on the T1 images, but am hoping to
apply the masks to the preprocessed PET images. I was looking at using
the “mri_gtmpvc” command to segment the choroid plexus using the mask
I already created but was hoping for some guidance.
There are also several options of preprocessed PET data I can chose
from, including “co-registered averaged standardized image and voxel”
including “co-registered averaged standardized image and voxel with
unform resolution” and “co-registered averaged” or “co-registered
dynamic”.
If anyone are willing to help or can connect me to someone how might
have time to reply or quickly chat, that would be great. I appreciate
the support and am looking forward to using PetSurfer.
