oh, sorry, you are correct. I guess you need to edit the aseg.presurf.mgz since that is what mri_fill is given as a segmentation. Sorry for the mistake Bruce On Tue, 26 Sep 2017, Gabor Perlaki wrote: > If I accurately understand the recon-all script, then -noaseg sets UseAseg=0, > but > "auto

Dear Bruce, Gabor, while reading this thread, I think that there is misunderstanding. -noaseg flag of recon-all indeed disables using aseg.presurf,  whereas -autorecon2-noaseg does the same thing as -autorecon2-cp (at least in dev version, looking at the recon-all code). Antonin Skoch Hi Ga

2017-09-26 Thread Gabor Perlaki
If I accurately understand the recon-all script, then -noaseg sets UseAseg=0, but "autorecon2-noaseg" is a different flag, which only sets the following things. case "-autorecon2-cp": case "-autorecon2-noaseg": case "-autorecon2-wm": set DoNormalization2 = 1; set DoSegment

no, I don't think that is the case. -noaseg sets UseAseg=0, which stops things like mri_fill from using the aseg, which is not what you want cheers Bruce On Tue, 26 Sep 2017, Gabor Perlaki wrote: > Dear Bruce, > > From the recon-all script it seems to me that autorecon2-noaseg, > autorecon2-w

Dear Bruce, >From the recon-all script it seems to me that autorecon2-noaseg, autorecon2-wm and autorecon2-cp are totally equivalent (the same flags are defined to be true in all three cases). Could you confirm this? Best regards, Gabor ___ Freesurfe

Hi Gabor you don't want to specify -noaseg. That tells recon-all not to use the aseg. I think autorecon2-cp and autorecon3 should do the trick cheers Bruce On Tue, 26 Sep 2017, Gabor Perlaki wrote: > Dear Bruce, > > I've corrected the lateral ventricles in the aseg.presurf.mgz and ran > "reco

Dear Bruce, I've corrected the lateral ventricles in the aseg.presurf.mgz and ran "recon-all -autorecon2-noaseg -autorecon3 -subjid". Although the labels in aseg.mgz is fine the surfaces (and midline cut) remained bad. Any other idea how to correct this type of error? Best Regards, Gabor
