Dana, There is also a '-bigventricles' flag which you can pass to recon-all, which affects mri_ca_register and mri_ca_label. Not sure of its efficacy though. Nick On Thu, 2009-04-16 at 14:54 -0400, Bruce Fischl wrote: > Hi Dana, > > the really huge ventricle subjects do sometimes fail with th

Re: [Freesurfer] Using a Label with Volume-based Monte Carlos

2009-04-22 Thread Nick Schmansky
Dave, I'm not 100% certain, but I think you need to create a mask volume from your subcortical.label file, and then use the --mask option with mri_glmfit instead of --label (see mri_glmfit --help). That is, create a volume with a '1' in the voxels of interest, and '0' elsewhere and pass that to -

Zhen, The -tal-check flag included with recon-all will perform the QA check that Avi mentions, with the addition of creating a z-score comparing the subject's QA score to a set of QA scores of known-good talairach alignments. The -tal-check flag runs by default in recon-all (in -all and -autoreco

Hi Jennifer, the spherical stuff has nothing to do with the CMA. And in fact the spherical registration itself is not based on any manual labelings, just estimates of cortical geometry from a set of training subjects. The cortical parcellations do depend on manual labelings, but this is also
