Hi Sita and Bruce, Sorry for this, it's the first time I post files here and I wasn't aware of the possibility you mentioned. Humyo sometimes acts like an idiot, but usually works (I make the files public and gave you direct links), sorry for that also. I've uploaded the data to the incoming direc

Hi Bruce, Please follow these links to get the dataset: http://www.humyo.com/7891739/C1_orig.tar.gz http://www.humyo.com/7891739/C1_modified.tar.gz The first one is the original before placing the control points, the second is the modified dataset after correction. Thanks a lot, and sorry for

Hi Gabor, recon2-cp currently starts *after* the aseg, so you'll need to rerun it from an ealier point than that. Try using -autorecon2 instead. cheers Bruce On Wed, 3 Mar 2010, Perlaki Gabor wrote: Hi all! We overlayed the aseg.mgz on the norm.mgz and put some controll points where the c

Hi all! We overlayed the aseg.mgz on the norm.mgz and put some controll points where the cerebellum segmentation was not accurate and we saved the controll points. We reran recon-all like this: 'recon-all -autorecon2-cp -autorecon3 -subjid our_subj' After that we checked the volume of cerebellum,

Hi Gergely, overlay the aseg.mgz on the norm.mgz in tkmedit and you can visually verify if it's accurate. If not, you can edit it with the tools in tkmedit. We do have some internal tools for VBM-style analysis but rarely use them as the results are so ambiguous. It should be easy enough to stu

2010-02-26 Thread Gergely Orsi
Hi all! We have processed 100 subjects with autorecon. I'd like to know how to check the cerebellum segmentation on the subjects. It would be crucial, because the images are a bit dimmer at the lower areas (it's far from the isocenter) and despite the intensity normalisation it still has lower int
