hi @araikes, glad to see you're enjoying the work.
dramatically improved not only my mouse templates
If you're enjoying those now, take a look at https://github.com/cobralab/optimized_antsMultivariateTemplateConstruction/ for a re-implemented template builder (DBM postprocessing in-progress....)
If anything ultimately comes out of using these (e.g., manuscripts), let me know how you'd like these scripts credited.
I guess for now, point at the repo. I have a sort of article of sorts in my head of "A non-random walk through scale space" which might eventually exist to describe my thoughts and the process of how these tools arose...
Is it as simple as
antsRegistration_affine_SyN.sh $moving $fixed dwi2struct_ --skip-nonlinear --linear-type rigid
?
Yes, --skip-nonlinear
will skip the nonlinear, and --linear-type rigid
will restrict the generated affine stages to only translation/rigid.
a _b_0 image (diffusion) and a T2 in
I haven't tried that combination before, as we don't work with DWI sequences much, so I'd be interested to hear how it goes.

Right now, I'm running everything in a Singularity container (for "ease" and version locking). The qbatch
requirement for the optimized antsMTC is a limiting factor there, I think.
Re: the other points... I'll certainly point to the repo for references and good that much understanding of the rigid registration was accurate.
I'll let you know how the DWI to T2 goes.
The qbatch requirement for the optimized antsMTC is a limiting factor there, I think.
Good news!
export QBATCH_SYSTEM="local"
makes qbatch just use gnu parallel locally. I tested the code developing it like that. You'll have to check your memory limits to get those right, otherwise it just runs as many commands as CPUs by default.
qbatch has a QBATCH_SYSTEM="container" method, where it passes commands into an "outer" qbatch, which submits jobs to run inside a container on a cluster, I wrapped MAGeTbrain with it, https://github.com/CoBrALab/MAGeTDocker/blob/master/mb-container
I'll have to look into that and see if I can get it operational. If I use QBATCH_SYSTEM="local"
, I'd likely need QBATCH installed inside the container, yeah?

Yup pip install qbatch
, and apt-get install -y gnu-parallel
Local QBATCH worked and I was able to generate the template (https://github.com/cobralab/optimized_antsMultivariateTemplateConstruction/). I know there's a lot of defaults.. Any optimal settings you've found with mice?
The defaults are intended to synthesize what I understand to produce the best results.
I suggest is to start with a reference image to define the orientation/resolution, including making one from one of the inputs if you don't have it (or constructing a rigid-only one or such to bootstrap).
Something I think would make things better, but I haven't proven, so it is not yet default is a gradient step schedule, https://github.com/CoBrALab/optimized_antsMultivariateTemplateConstruction/issues/5
@gdevenyi,
First, thanks for all of the exceptionally cool improvements you make to existing programs.
ants_generate_iterations.sh
andantsRegistration_affine_SyN.sh
are fantastic and have dramatically improved not only my mouse templates but also the registration of those templates to standard spaces.Two things:
antsRegistration_affine_SyN.sh
. Is it as simple asantsRegistration_affine_SyN.sh $moving $fixed dwi2struct_ --skip-nonlinear --linear-type rigid
?
