Hi Andras,  
thx for the quick response.  
If I change the “Transform” tag in the txt file to “AffineTransform\_double\_3\_3”, it correctly load the transform. The problem is that this txt file is part of the output from ANTs template building. I could manually correct this tag in all the files (e.g. with a script), but in the past, these files were loaded without error. In fact, I remember that I [had this error before](https://discourse.slicer.org/t/affine-matrices-insight-format-with-tag-matrixoffsettransformbase-double-3-3-cannot-be-loaded-into-slicer-anymore/2302), and back then, it was identified as a bug and it was fixed.  
Would you recommend me to change this tag in all files?
