Re: [Freesurfer] question re: ventromedial and dorsolateral frontal lobe volumes
Hi Anne, Within our parcellation system, the medial orbitofrontal cortex roughly corresponds to the ventro-medial frontal area. Though there is no explicit region of interest for the dorsolateral prefrontal cortex within our parcellation system per se, you can either measure it yourself (which may be slightly painful if you have a large number of subjects) or use the rostral middle frontal ROI, which encapsulates the DLPFC.

Re: [Freesurfer] multi-channel lesion segmentation.
Hi Mehul, we have a dev version of something that does this, but it's not ready for release yet. sorry Bruce On Tue, 18 Sep 2007, Mehul Sampat wrote: Hi all, I would like to segment lesions using both T1 and FLAIR images.

[Freesurfer] multi-channel lesion segmentation.
Hi all, I would like to segment lesions using both T1 and FLAIR images. I think this is not possible with the current version of freesurfer. Is that right ?

[Freesurfer] pictures from the freesurfer digest
Hello all, I am subscribed to the freesurfer list in digest format. If someone sends pictures to the list I am not able to see/open them from the digest or from the archives. Is there an option I need to change? Or do I need to switch off digest mode completely? Thanks in advance, Chris Bell ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
[Freesurfer] legacy data and FDR
Hi, Is it possible to use FDR in stable3 for data that was processed prior to the introduction of brainmask.mgz? It seems like I can view the data just fine in stable3, or stable2 for that matter (though not stable 4), but FDR gives results that seem wrong. FDR sets the threshold to -log10(p)=4.279537 [p=.5] no matter what the starting pvalue is. Thanks, Rob -- Robert P.
