QDEC does not allow it, but you can do it with mri_glmfit with the --pvr option. Run mri_glmfit with --help to get more info. doug On 01/25/2015 11:16 AM, angela.fav...@unipd.it wrote: Hi all, I wrote a paper about gyrification in a sample of malnourished patients. I found only little overlap

Hi Doug, thank you for this hint. I have included --pvr in my mri_glmfit command using a stack of cortical thickness maps of the same hemisphere (and same subjects in the same order). I also added a column in my design matrix. It seems to work. Only when I use the mri_glmfit-sim command, this

That's fine. mri_glmfit-sim has a little anxiety when it finds mri_glmfit options it does not recognize. doug On 1/26/15 5:00 PM, angela.fav...@unipd.it wrote: Hi Doug, thank you for this hint. I have included --pvr in my mri_glmfit command using a stack of cortical thickness maps of the

Hi all, I wrote a paper about gyrification in a sample of malnourished patients. I found only little overlap between maps of significantly rediced cortical thickness and maps of significantly reduced gyrification index (in comparison to a group of healthy controls). One of the reviewer raised the
