I'm running into problems with the New Segment procedure in SPM8. I keep on obtaining a fine ring of dura around the grey matter native segment image even after messing with the bias and regularization parameters. The data were collected on a 3T and are good quality. I don't run into the problem with the old segment. Any way to get around this problem? I'd like to use the New Segment to DARTEL routine.
Thanks to any and all,
Jeff Browndyke
