Generally, during mri_ca_registe= r, I end up with a segmentation fault of the following: ----------------- gca peak Unknown =3D 0.94091 ( 0) gca peak Left_Inf_Lat_Vent =3D 0.14709 (39) gca peak CSF =3D 0.14344 (47) gca peak Left_Accumbens_area =3D 0.20088 (67) gca peak Left_undetermined =3D 0.98433 (34) gca peak Left_vessel =3D 0.32698 (60) gca peak Left_choroid_plexus =3D 0.11007 (56) gca peak Right_Inf_Lat_Vent =3D 0.20176 (34) gca peak Right_Accumbens_area =3D 0.32293 (69) gca peak Right_vessel =3D 0.36466 (58) gca peak Right_choroid_plexus =3D 0.09865 (51) gca peak Fifth_Ventricle =3D 0.66382 (40) gca peak WM_hypointensities =3D 0.12408 (82) gca peak non_WM_hypointensities =3D 0.07897 (54) gca peak Optic_Chiasm =3D 0.38389 (74) Segmentation fault [swmed-xryrdix93:CorrectedBrainsGE/TBI/St43] teresa% =20 --------- I can forward a recon-all.log of this subject. I've also had some major = issues with intensity inhomogeneities where the pial, wm, and orig = surfaces will not pick up the sulci in certain regions of the cortex (the = wm -aux volume just looks like one big blob of grey). I've tried using = -nuiterations 4, 150, etc., but have not had much success. =20 Any suggestions would be greatly appreciated.
