Hi Satra,

I don't think any labels were manually edited. If control points were added they would be stored in each subjects' tmp/control.dat file. Similarly, the wm edits are tracked in the wm.mgz volume. Voxels that are erased are set to 1 and those that are turned on set to 255. It's self-documenting :). You could use this info to generate a summary across the study, but we haven't done so. If you feel moved to build such a tool and contribute it we'd be happy to distribute it :).

cheers, Bruce

Is there any documentation for the OASIS freesurfer-processed data? I'm looking for details of human intervention. For example,

• were seeds inserted for any brains?
• was the white matter edited
• were cortical labels manually edited for correctness?

Any documentation about the whole process would be much appreciated.

Thanks,

Satra
