External Email - Use Caution Hi everyone,
I am confused by the two types of registration files: .lta and .dat. .dat file is simpler and easier to understand. But for the .lta files, there seems to be no detailed explanation regarding it. Can anyone point out to me where can I find the detail explanation of the file? And, what's the relationship between .lta and .dat file? Also, .lta files seem to cause some compatibility issues. For example, if I use the tkregister2 utility to make some changes to the registration file of type .lta (generated by bbregister), like below tkregister2 --mov $someSeries --reg $SUBJECTS_DIR/$subjectid/mri/transforms/FLAIR.auto.lta --surf pial and save it from the GUI, then many errors occur in the console window, like below: ...... MatrixAsciiReadFrom: could not scanf parms ERROR: TransformLTA2RegDat(): type = 2011264000, must be 1 or 0 or 14 Segmentation fault (core dumped) Actually that is because the registration file has been saved in the format of .dat, although the file extension is still .lta, and the tkregister2 program finally cracks when reading the newly saved .lta file. Anyone can solve my confusion? Thank you!
