Hi Stephanie
it depends what you want to compute the mean over.

Thanks for your answer, Bruce!
I wasn't aware that it extracts data straight from the surface image. I was
wondering which image type I would have to specify with mris_anatomical_stats
if I wanted to use it to extract FA values from dti_FA.nii.gz.

Thanks! Can you please upload one of the subjects that fail?

Hi,
The hippocampus subfields division problem happens on more than one
subjects (~10). However, I have successfully run it on one subject (which
is a little earlier in time, before I failed to run recent 10 subjects).
Thank you for your help.

Dear Freesurfers,

The image quality is quite good. GM and WM contrast is excellent. There are
no scanning artifacts. The only remarkable finding is that this individual
has moderate brain atrophy, enlarged ventricles, and large white matter
signal abnormalities
What version of FS are you using? version 6 initializes with mri_coreg (the FS
equivalent of spm_coreg). On whole-brain data, I've found this to be very
robust. Is your data whole-brain?

Dear Eugenio,
thanks for getting back to me!
Yes, the same error seems to happen for all subjects for which I have only one
time point. The longitudinal processing pipeline (recon-all base, recon-all
long) went fine for these subjects, and I can
Hi Mona, when you run fcseed-config you can specify to use -mean or -pca npca.
-mean produces the mean waveform. -pca will run a PCA on all voxels and take
the first npca components. In principle, using more components will fit more of
the noise. But it can also make the design more poorly

Hi Yixin,
Does this happen for all subjects, or only one?

Thanks a lot for your email, Saskia.
Does this happen for more than one subject? Can you reproduce the error?

Hi
I have a problem very similar to this one:
