antsApplyTransforms with c3d-converted affine: itk::ERROR: TxtTransformIOTemplate(0x2912350): Could not create an instance of MatrixOffsetTransformBase_double_3_3

[sgiavasis]

Hello,

I am trying to run antsApplyTransforms where one of the transforms is a c3d-converted affine from FSL FLIRT (.mat -> .txt). When I run the command I get this error (the final --transform, affine.txt is the one in question):

The file that the c3d_affine_tool created, affine.txt, contains this:

Insight Transform File V1.0

Transform 0

Transform: MatrixOffsetTransformBase_double_3_3
Parameters: 0.999937 0.00118774 -0.0111388 -0.00188052 0.99805 -0.0623922 0.011043 0.0624092 0.99799 -1.25486 -30.7644 -31.7582
FixedParameters: 0 0 0

So c3d_affine_tool is creating a type of transform which is not included in that list which the antsApplyTransforms error message provided. At first we thought this may be a c3d_affine_tool version or ITK-SNAP version issue, but even with the nightly build version of c3d this still happens.

Any help would be appreciated. Thank you!

MatrixOffsetTransformBase_double_3_3

is a base class and should not be passed to antsApplyTransforms.

you should pass a "real" transform, i.e. affine, rigid, etc.

though i did note that "MatrixOffsetTransformBase_double_4_4"

is listed ... probably should not be. there are work-arounds:

1. change the txt file to contain a compatible type e.g. affine or rigid or
   whatever.

2. use a mat file

3. register MatrixOffsetTransformBase_double_3_3 yourself

we moved away from txt files b/c they lack precision.

also, no guarantees of correctness when mixing tools.

The file that the c3d_affine_tool created, affine.txt, contains this:

So c3d_affine_tool is creating a type of transform which is not included
in that list which the antsApplyTransforms error message provided. At first
we thought this may be a c3d_affine_tool version or ITK-SNAP version issue,
but even with the nightly build version of c3d this still happens.

Any help would be appreciated. Thank you!

Thanks for the quick response!

I'm going to try out some of your suggestions and post back.

[sgiavasis]

As a quick test, I changed the text file to contain a compatible type. When I tried to use it, I got an error. I shelved it for a second and just tried the same command with a rigid or affine .mat produced by antsRegistration (a product of a functional to anatomical registration) and got the same error:

Can't read initial transform /home/likewise-open/CHILDMIND/steven.giavasis/deleteThis/transform1Affine.mat

This is in an attempt to register a functional timeseries to a template. I am providing three transforms: 1. an ANTS-generated affine from anatomical-to-template, 2. an ANTS-generated nonlinear warp from the same anatomical-to-template, and 3. the functional-to-anatomical (which is what is throwing the error).

And as above, 3. (the func to anat) throws this error whether I use a c3d-transformed affine or an affine created by antsRegistration.

Any idea what could be tripping up, or how I could go about finding more information about the error?

[stnava]

sounds convoluted. no ideas. might want to provide the data then i can
give you the right commands --- but sorry cant help with c3d.

sounds convoluted. no ideas. might want to provide the data then i can
give you the right commands --- but sorry cant help with c3d.

As a quick test, I changed the text file to contain a compatible type.
When I tried to use it, I got an error. I shelved it for a second and just
tried the same command with a rigid or affine .mat produced by
antsRegistration (a product of a functional to anatomical registration) and
got the same error:

Can't read initial transform
/home/likewise-open/CHILDMIND/steven.giavasis/deleteThis/transform1Affine.mat

This is in an attempt to register a functional timeseries to a template.
I am providing three transforms: 1. an ANTS-generated affine from
anatomical-to-template, 2. an ANTS-generated nonlinear warp from the same
anatomical-to-template, and 3. the functional-to-anatomical (which is what
is throwing the error).

And as above, #3 #3 throws this
error whether I use a c3d-transformed affine or an affine created by
antsRegistration.

Any idea what could be tripping up, or how I could go about finding more
information about the error?

The example you linked helped me get this working, actually. When I created the anatomical-to-template warps in the script above and then ran the antsApplyTransforms, I got a registered functional that was off-center.

But I added my functional-to-anatomical affine (the c3d-converted one, hand-edited to have an 'appropriate' transform type) as a third transform to the antsApplyTransforms command, and it worked! The only difference ended up being the two anatomical warps (the 1Warp and 0GenericAffine).

My original anatomical warp transforms that did not play well with the functional-to-anatomical in antsApplyTransforms were created with antsRegistration parameters gleaned from the antsIntroduction.sh script. I'm curious- are the parameters in the script above fine-tuned for mapping fmri to template? Why were they chosen? etc.

Thanks for your time!

glad it worked for you. no fine tuning. the parameters in the example
were just chosen to be fast.

Got it. One last semi-related question- antsApplyTransforms doesn't accept a dimension argument of 4 for timeseries I noticed- does this mean you are keeping WarpTimeSeriesImageMultiTransform around for now?

Also I would call this issue resolved if you need to close it.

WarpTimeSeriesImageMultiTransform is deprecated and may be removed.

antsApplyTransforms covers transformation of

scalars, vectors, time series and tensors

@sgiavasis could you point me to code (C-PAC) which is doing the FSL .mat to ITK conversion that worked for you at the end?

Hi There,
I would like to register two T1 structural Images. First, I manually registered them by ITK-snap. But when I want to register them by ANTs, I get an error (I have attached pictures).
any help would be appreciated.
