[Freesurfer] cross sectional vs longitudinal TRACULA reliability

External Email - Use Caution Hello, I’ve run both longitudinal and cross-sectional TRACULA pipelines on the same dataset, and I’ve found surprisingly low correlations of FA measurements for several tracts (as low as r= .1 in some cases). Which measurement should be considered m

[Freesurfer] longitudinal TRACULA -prep error

External Email - Use Caution Hello, I'm running into an error in the longitudinal TRACULA pipeline that I'm not sure how to resolve. I saw this error in the message board but there was no resolution to the problem so I thought I'd ask again. I've successfully run the recon-all

[Freesurfer] -make all error

Hello, I am running recon-all for several subjects’ 7T data using Freesurfer version 6.0 and currently trying to ensure appropriate skull stripping and pial/wm surface generation. For a few participants that needed some control points added and for which I reran them through the –autorecon2-cp

[Freesurfer] TRACULA -stat coord output file

Hello, Are the contents of the *.coords.mean.txt file generated from the trac-all -stat command, the average MNI coordinates along the tract across subjects? Or average coordinates in native space? Thanks! Carissa ___ Freesurfer mailing list Freesu

[Freesurfer] TRACULA path segmentation fault error because of bedpostx?

Hello all, I've been running trac-all from the command line without the configuration file since I'm not changing any defaults. I've successfully run several subjects through the trac-all -prep stage, and the -bedp stage. **Although I never got the "trac-all -bedp finished without error" prompt
