Thanks Bruce and Cesar!
The problem is I have analyzed a part of my data with 5.1, and I am collecting new data, so I am wandering should I also analyze new data with  5.1, or should I rerun old data (as well as new data) with 5.2.
 
Now it seem to me that keep it consistent is most important and should be OK, but 5.2 may be better?
 
Thanks again!

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
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
