Can't read MATLAB Transform

[muschellij2]

Couldn't read MATLAB transform with current ITKR/ANTsRCore build (installed using devtools::install_github):

tx = readAntsrTransform("matlab.mat")

ITK ExceptionObject caught !

matlab.mat.gz

[stnava]

R.matlab says:

> readMat( "/mnt/c/Users/bavants/Downloads/matlab.mat")
Error in readMat5(con, firstFourBytes = firstFourBytes, maxLength = maxLength) :
  Reading of MAT v7.3 files is not supported. If possible, save the data in MATLAB using 'save -V6'.

probably the same thing here but with a much worse message. reading a .mat written by ANTsR seems to work still.

Fails also with MAT version 6.0 files from MATLAB mv6.mat.gz :

R.matlab::readMat works

i dont think this is a proper transform file. at least not according to antsr/ants .... how was it created?

[muschellij2]

It's not one from ANTsR. I'm saying that ITK has a read function for MATLAB mat files that I thought ANTsR used to be able to read but the linking doesn't seem to work now. John

Ok: maybe test to see if old versions work? On Wed, Apr 17, 2019 at 4:02 PM John Muschelli <notifications@github.com> wrote:
