Hi all - I have just posted a tracula software update. This update adds some new functionality without any changes to any existing functionality, so you can use it with any analyses you have already done in 5.3.
What's new: 1. Compute measures of head motion, as in our recent paper: http://www.sciencedirect.com/science/article/pii/S1053811913011312 2. Makes it easier to perform "along-the-tract" type analyses by combining the FA/MD/etc values from multiple subjects by position along each tract. 3. Gradient vector tables can now be different for each scan, they can be formatted in columns or rows, and blank lines at the end of the table should not pose a problem. 4. Fixed a small scripting bug that was causing the longitudinal stream not to run at all on certain platforms. You can get the update here: http://surfer.nmr.mgh.harvard.edu/fswiki/Tracula#Updates Download the file for the appropriate platform (same as your freesurfer 5.3 distribution), unzip it, and copy the files directly into your $FREESURFER_HOME/bin. The trac-all wiki page has been updated, with the new command-line options shown in red: http://surfer.nmr.mgh.harvard.edu/fswiki/trac-all#Arguments The tracula tutorials have also been updated with info on how to use these new features. Specifically: 1. For measures of head motion, see "Outputs from quality assessment" in: http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/TraculaOutputs 2. For along-the-tract analyses, see "Anisotropy and diffusivity along the trajectory of a pathway" in: http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/TraculaStatistics 3. For new options for specifying gradient tables, see "Specify the diffusion-encoding gradient table" in: http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Tracula Enjoy and thank you for your feedback, a.y _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.
