You can run it like that or with --osgm (instead of --fsgd and --C), osgm = one sample group mean.

Hi Doug, I have pasted the correspondences below. My question is, if I want to identify the PCs in a group for a single modality (PET), how should I run the mri_glmfit? A single group design with A contrast of 1 0 (for a nuisance covariate)? Thanks ! Elijah Doug: For within modality, you can add --pca to mri_glmfit (run it with --help to get more info). We do not have ICA tools in FS. On 12/01/2016 02:04 PM, Foo Keat Mak wrote: > Hi Freesurfer Team, > > For a given group, I want to look at the covariance patterns between > thickness and PET.

ICA analyses looking at the covariance patterns across modalities?

Thanks Doug. Does that mean that a one group design? With a contrast of 1 0 (adjusting for one variable)?
