Hello FreeSurfer experts, I am currently trying to systematically investigate the differences in cortical and subcortical estimates that occur when performing recon-all on one scan, or when averaging across scans of varying quality with regard to movement.
I have a list of subjects that each have been processed (recon-all) twice (once with one scan and once with two scans), and would like to run some FreeSurfer statistical analysis on them. Is it feasible to set up a longitudinal analysis similar to the one described here: (http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/LongitudinalTutorial)? If it is, could someone assist me in setting this analysis up? (I have tried following the tutorial, where I on each subject set "0 years" for one scan, and "1 year" for two scans in the QDEC table, but the results from the QDEC analysis don't seem to agree with previous SPSS results that I have). Thank you, Joy-Loi _______________________________________________ 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.
