Matt,
Yes, I think the plan is to discuss this and other potential options. I had a feeling you may know the most, but I thought I would send out the question in case anyone else has tried. As it stands, it sounds like no method currently exists for a Caret surface-to-Freesurfer transition?
I am still trying to understand Freesurfer basics, but it sounds like the longitudinal pipeline generally requires the same input data as across-subject. My hope is that, since the surfaces are already constructed, I can avoid the need for an (infant) atlas, but I am still figuring out what that means in terms of files I need/conversion/etc.
Thanks for your help, and I look forward to further discussion this afternoon.
Kara

She wants to go from Caret to FreeSurfer, rather than from FreeSurfer to Caret, which is what I do.
Kara, I believe we are meeting tomorrow to discuss the options for this?
I don't know anything about the FreeSurfer longitudinal pipeline, but it would take going through the pipeline and finding all of the inputs needed and converting them or generating them. I think the main goal here is to use the longitudinal surface registration.
Matt.

Hi Kara
I think the answer is yes as there are people at Wash U that do this routinely. Maybe Matt Glasser or someone else can chime in?
cheers Bruce

I am new to Freesurfer, and I am trying to input/process preterm infant brain data (ultimately attempting longitudinal registration). I already have surfaces generated from Caret, as well as the original T1/T2 images. My question is: Does anything exist to take processed data from Caret into Freesurfer? If not, is there a good way to process the T1/T2 images in Freesurfer despite the differences in contrast and intensity (and anatomy)?
Thank you in advance for your advice, Kara
