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, and back then, it was identified as a bug and it was fixed.
Would you recommend me to change this tag in all files?
