[Freesurfer] what image should I finally work with?

2012-12-13 Thread Prasanna M
I ran Freesurfer on OASIS longitudinal data with the longitudinal pipeline. I want to work with the full brain image (with gray level intensities) which is intensity normalized and skull stripped and all the timepoints of a subject are rigidly registered to the 1st time point. There were many brain

2012-12-07 Thread Prasanna M
Hi, Do I work with aseg.fused.mgz or do I work with aparc files to get the most accurate segmentation of brain structures? I tried using freeview to look at segmentations. Is there a way to isolate mgz files of very specific structures. I mean, is there an inbuilt tool which can do that for me, o

[Freesurfer] Regarding freesurfer segmentations for longitudinal data

2012-11-27 Thread Prasanna M
Hi, I work in the area of longitudinal shape analysis, and have used the longitudinal OASIS data in the past. I was trying to find freesurfer segmentations of structures for the OASIS data, but could only find them for cross-sectional ones. I write to you to ask if you're aware of segmentations ma
