Hi Hengameh
By far the most common reason for this is running out of disk space.

Hi Sofia
Unfortunately that doesn't really work as the most time-intensive steps are
required. We are working on replacing some of these with deep-learning
equivalents, but it will be some months before that is available.
Sorry

Hi Jan
If you create a family template you will only be able to compare within family,
unless you also align the templates I guess?

Hi John
1. We empirically set it at 2, but that was a long time ago, but the optimal
number is dependent on a lot of things, mostly image CNR. If the gray/white
contrast is good enough you can run it for more, but you have to make sure that
the
a path, the path would curve around instead of
cutting straight across.

Hi Bruce,
Adding -distance 20 20 definitely helped (see the attached file). Even
though, the outcome is still different than
p.s. adding -norand won’t fix the failed flattening, it will just make it
repeatable. In my experience (admittedly a long time ago now), adding more
distances and longer ranges fixes this problem

Can you try running it with -distances 20 20 added to the command line?

Hi Shahin
What is your command line? mris_flatten does some random sampling of distances
since the whole N^2 distance matrix is too big. You can remove the randomness
by either specifying -norand or using a specific seed like -seed 1234.
That said,
Hmmm, trying mri_convert file.nii.gz file.mgz
Then give file.mgz to synthstrip. I thought it would work with nifty, but maybe
not?

That is what mri_synthsr does (which is part of the FS distribution)

Hi Rob
Can you run mri_info on that volume? And just ls -l to see if it is a
reasonable size?
