If you run mri_segstats --qa-stats subject subject.qa.dat It will generate the QA .dat file. This will have 20 numbers in it. Run mri_segstats --help to see what they are. I usually use #20 (CNR) Run it for all your subjects, then sort by CNR, then examine the worse subjects

External Email - Use Caution

Hi all,

I am processing a large longitudinal dataset of T1-weighted anatomical images through the recon-all pipeline (N=680). I know that the gold standard for quality control following recon-all is visual inspection of the output surfaces and parcellations. However, given the large sample size, I was writing to see if the community has any recommendations for automatic QC pipelines.

I read a few papers discussing the use of Euler numbers to detect outlier datasets for exclusion (see citations below). Does anyone have any other recommendations?

Thank you in advance!

Best, Jenna
