Hi,
tried to use control points to improve the segmentation of the putamen in the difficult area between putamen,claustrum & insula. adding some white matter control points does not seem to insluence the aseg segmentation. control points are set to 110 after reprocessing with recon-all -autorecon2-cp -autorecon3 -subjid 008 ( v5.1), but these same points are still labeled as putamen?
also i do see that some white matter filaments have leaked into the putamen, so the mailing list comments that control points would mess it up seems it would be correct ( if it was affecting the putamen seg, which it does not seem to have done at all).
so options are manual editing, here ask opinions, the extra tissue added between the putamen&insula it is doing consistently, so taking the unedited volumes, after checking there are no odd other things added or missing might be more unbiased estimate, that volumes after several human raters had selectively removed a few voxels here and there ?
any opinions ?
thanks
greg
