Hello FreeSurfer Developers,
I have compared two groups in area, volume and thickness (using mri_glmfit and mri_glmfit-sim) and I want to extract the total value from each significant cluster so that I can run analysis with behavioural variables in SPSS.
I have found some previous posts with the following command:
mri_segstats --i <pathway to rh.volume.Study.10.mgh> --seg cache.th13.abs.sig.ocn.mgh --excludeid 0 --sumwf ClusterVolumeValues.dat –accumulate.
but also the alternative option in --seg cache.th13.abs.y.ocn.dat.
Could you please tell me: 1. Which is the correct option for -- seg and what is their difference?
2. I tried to run both option and I get the exact same error:
mri_read(): couldn't determine type of file lh.SexStudy_area.glmdir/MN-FM/cache.th13.abs.y.ocn.dat ERROR: loading lh.SexStudy_area.glmdir/MN-FM/cache.th13.abs.y.ocn.dat
Any ideas of how to resolve that?
3. Is that command the right one for volume, area and thickness?
Thank you in advance,
Best, Georgina
