[Freesurfer] mri_robust_template always fails in fmriprep when aligning multiple T1 images (Return code: -9)

2019-07-22 Thread Frederick, Blaise B.
Dear Freesurfer experts, I’m running into a problem with mri_robust_template when trying to align multiple T1 images (this is with Freesurfer 6.0.1). I’m using fmriprep 1.4.1 to preprocess subjects from the OASIS3 dataset (or at least, attempting to). Each subject has 5-7 T1 scans over 3-4 tim

External Email - Use Caution Hello Freesurfer support team, I am trying to create accurate white/pial surfaces, however, due to signal drop-out, Freesurfer is consistently underestimating the pial surface -- a problem which I am only able to fix using control points. Unfortunately

In most of the tools there is an option to invert the matrix before you apply it. If you save the registration matrix as an LTA instead of DAT, then most of the tools will figure out the directionality. On 7/22/19 4:24 PM, Sam W. wrote: > > External Email - Use Caution > > Hi, > I would
