Hi, In reconstructing some normal adult MPRAGEs, I've had a couple of different fairly large errors that I haven't been able to fix: (1) In a handful of subjects, more than half of the brain is lost, I think during the skullstripping step (ie, isn't present on the white matter or brainmask volumes later). This seems to be primarily on scans from a 3T Siemens with a 32channel head coil. I have tried adding control points, but this doesn't help. (2) In another handful of subjects, a large portion of the cerebellum is designated as cortex, and is labeled on the aseg maps.
Any suggestions on how to fix these two types of problems? thanks, Nicole -- Nicole Senecal Neuroscience Graduate Group Kable Lab 3720 Walnut St., Room C37 Philadelphia, PA 19104 Lab phone: 215-746-4371
