Missingness and recent developments in longitudinal pipeline for pediatric samples
by Mohn, Johannes 27 Aug '18

27 Aug '18

External Email - Use Caution Dear FS Experts and Community, we are working on a longitudinal dataset of structural T1w images in a pediatric sample assessed at 2 waves, 2 years apart (aged 6/7 and 8/9). As far as we know, it is yet unresolved whether the Freesurfer longitudinal pipeline is robust in pediatric samples, where the head size is still changing or have there been any recent developments? Also, is there any documentation on how missingness affects this Pipeline? We look forward to your response Thank you, Laurel and Johannes Jacobs Entwicklungsstudie Max-Planck-Institut für Bildungsforschung Max Planck Institute for Human Development Lentzeallee 94 14195 Berlin Tel.: 030-824 06 371 E-Mail: jacobs-studie(a)mpib-berlin.mpg.de<mailto:jacobs-studie@mpib-berlin.mpg.de>

Seeing the Parcels as Volumes
by Maedeh Khalilian 27 Aug '18

27 Aug '18

External Email - Use Caution Dear FreeSurfer experts, I have used "mri_annnotation2label" and "mri_label2vol" to change the parcellation output of FreeSurfer e.g the lh.aparc.annot into an ".nii" so i can see the parcels in Mricro. Now I can see the parcels just on the cortex not on the whole graymatter. The first question I have is that, is the parcellation done on the whole graymatter? And if yes, is there a way that I can see the volumes on the whole graymatter, not just on the cortex? I would be grateful if you could help me. best regards, Maedeh,

Do you think I have to change some setting to run it? Also, I've looked for solutions and couldn't find a one which really fits my problem. Would you please help me trouble-shoot this issue?
