[RESOLVED] HCP longitudinal question

Use Questions
1

Hi Jure,

I understand that the longitudinal stream is not yet available (though it looks like a lot of progress has been made recently). Once it is available, will the longitudinal stream have any impact outside of the structural pipelines?

For example, will the functional pipelines continue to rely on the outputs from the cross-sectional structural processing or will they use the longitudinal versions of the segmentations, surfaces, myelin maps, etc.?

Thanks!

Hi djr,

Structural longitudinal processing (HCP Longitudinal FreeSurfer) is coming out later this week or early next week (both in QuNex and in HCP Pipelines!). I do not know from the top of my head if the results coming out of the longitudinal FS pipeline are already wired into HCP pipelines that follow structural processing (e.g., surface, volume or diffusion preprocessing). I can check this out with our HCP colleagues, if that is what you are asking?

Best, Jure

Thanks! Yes, that’s what I’m asking.

Hi,

I just talked with researchers behind HCP, they said that on piper it would be possible to rewire everything so downstream pipelines would use longitudinal inputs but it is not yet officially supported. Longitudinal processing of downstream pipelines is in development and will be enable one command at a time.

Best, Jure
