It doesn't matter, just make sure to be consistent. Use the same system, the same computer setup, and the same system version, etc. Analyzing data in parallel is always recommended with large sample sizes like yours

Thank you for your response. My next question is regarding the analysis process. I am curious to know if there is any difference between analyzing one specific subject and analyzing multiple subjects in parallel. For instance, if I am working on 1000 subjects, would it make a difference in the volumetric results if I analyze all of them at once in parallel or break them down into smaller groups to analyze? I would greatly appreciate your help with this.
Thank you and Best Regards,
Yunus.

Hi there,
My name is Yunus and I'm currently working on my Ph.D. thesis, which involves analyzing the HCP database volumetrically using Freesurfer. However, before I begin with the software, I was wondering if there is a tool in Freesurfer that can perform a quality check on the data to identify any possible artifacts or noise that might affect the analysis.
Could you please let me know if such a tool exists in Freesurfer? Your help would be much appreciated.
Thank you and Best Regards,
Yunus.
