Hi Mads
yes, you should be able to use mri_convert to change it to .mgz format and name it brainmask.mgz, after which I think it will look as if you've manually edited it and it will be applied

I got a skullstrippen mask from another pipeline to remove the noise in the MP2RAGE. Is it possible to give that to the recon-all? it is either a mnc or nii
thanks, mads

I think the standard MP2RAGE only generates the T1 image on the scanner. With the Bloch simulation you can also figure out PD but the online image analysis doesn't do it.

I thought mp2rage lets you derive a proton-density (PD) weighted image, but I could be wrong. I'll cc Andre van der Kouwe who will know

Hi and thanks for the fast reply.
Pardon my ignorance, but I am not sure that the PD images are?
thanks, mads

Hi Mads
my guess is that this is a problem with the MP2RAGE. We don't see this in the mprage or memprage. Can you look at the PD images in that region? Is the PD close to 0? Maybe you can threshold it out? That region is usually very dark on an mprage

Hi,
I got a problem with recon-all of T1's. The problem is that the surfaces extent into what is essential noise, see linked images. The problem is reoccurring in all the subjects I have ran so far, so I was wondering if there could be a generic fix or if it will be necessary to fix each recon individually.
The sequence is a MP2RAGE recorded from a Siemens Skyra.
thanks, mads
