Freesurfer experts,

I have attached the recon-all log from the scan I included an image of in my previous email. Any suggestions on how to deal with dilated ventricles when the -bigventricles flag is not sufficing would be deeply appreciated.

Thank you.

Dear Freesurfer experts,

I have run recon-all and included the -bigventrcles flag on a number of brains with ventriculomegaly. This fixed the segmentation errors in a few cases; however, there are still brains with dilated ventricles for which recon-all is not providing accurate segmentation (see attached image).

Are there any other tricks I can attempt to solve this issue? I was considering doing manual pial and white matter edits in conjunction with filling the ventricles by using the Edit Voxels Tool. Would this be advisable?

Thank you!
Victor
