[Freesurfer] Problem to understand QA tool results.

Dear freesurfers,

I performed cerebellar segmentation on 100 subjects. I don't detect any problem when checking the segmentation with tksurfer and tkmedit. I used the option -gen-asegLUT with QA tool. I have several error messages and but I'm not able to understand them.

1) I have several outliers in every t1 image and this message for example : "checking subcortical label: Left-Cerebellum-White-Matter, . +/- . as100351_conv Left-Cerebellum-White-Matter value 1.209679200 is an outlier (avg = . +/- .).."

I don't know how to interpret this message, and how to correct the outliers.

2) I have this error message "ERROR: Actual file order disagrees with common file order for subject as100351_conv" QA tool suggest to use this command "recon-all -make all -subjid as100351_conv", but this command doesn't seem to work.

Please find below the full recon checker message.

Thanks a lot for you help, I wasn't able to find a wiki or any web page to help me understand the message of QA tool. The first question has already been asked in august I think, but remained unanswered.

ERROR: Actual file order disagrees with common file order for subject as100351_conv

At least one step in the recon-all stream has been skipped or rerun out of order. Run the following command to rerun any steps which were skipped or for which the output has been modified.

recon-all -make all -subjid as100351_conv

Alternatively, examine the ReconAllTable for your version of FreeSurfer to identify the recon-all step where the discrepancy is occuring and rerun every recon-all step from that point forward. This subject may have been processed with a different version of FreeSurfer other than the version used to create the common file order file (based on v5.1 by default if not specified by the user). Consider generating an output file order file for your specific dataset using the 'genoutputorderfile' flag. See the '-help' flag for details.
