External Email - Use Caution Thanks Doug! I'll use lta then, but which tool do you recommend I use for inverting the matrix in order to have a freesurfer-to-diffusion registration matrix? bbregister does not seem to offer the option to invert matrices. Is tkregister2 the preferable tool to use here? I realize there is an --lta-inv ltafile option. Would this be correct?:
tkregister2 --mov B0.nii.gz --fstarg --fslregout fsl.mat --s sub01 --lta-inv reg.lta I'd like to output an FSL-style registration matrix because I intend to use some of FSL tools. Thanks for your help!
