Hi Inga,
Sorry, I missed this message on the mailing list.
This is a new issue to me, so I will take a look at the label fusion step.
And yes, we are working on including T2w images in the pipeline as at the newborn stage it would help with the GM/WM segmentation accuracy.
Best, Lilla

External Email - Use Caution
Hello experts,
I've begun using infantFS for neonates and I'am interested in the subcortical segmentation.
I noticed that the internal capsule is delineated in the manseg-tsubj2subj.NIFTYREG volumes (irrespective of the template's having gmwm or not), but that ist lost after mri_label_fusion when the thalamus has suddenly increased, swallowing PLIC and corona radiata, the basal ganglia have also expanded and the corpus of the caudate nucleus is large and pushed upwards.
Is there a way to preserve the subcortical anatomy?
Would labelling e.g. capsula interna help? Is there a way to include 2D T2axial to help with gmwm contrast?
Best regards, Inga.
