Dear Freesurfers, I just read this paper about freesurfer version and operating system matters: Gronenschild EHBM, Habets P, Jacobs HIL, Mengelers R, Rozendaal N, et al. (2012) The Effects of FreeSurfer Version, Workstation Type, and Macintosh Operating System Version on Anatomical Volume and Cortical Thickness Measurements. PLoS ONE 7(6): e38234. doi:10.1371/journal.pone.0038234 http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0038234 I am running freesurfer on linux system, and installed both version 4.5 and 5.1, and currently using 5.1. So which version is most recommended? should I use other versions like 5.0 or the coming 5.2? Any suggestion is appreciated
