Splice or merge sets of directions over multiple shells into a single set, in such a way as to maintain near-optimality upon truncation
dirmerge [ options ] subsets bvalue files [ bvalue files ... ] out
- subsets: the number of subsets (phase-encode directions) per b-value
- bvalue files: the b-value and sets of corresponding files, in order
- out: the output directions file, with each row listing the X Y Z gradient directions, the b-value, and an index representing the phase encode direction
- -unipolar_weight set the weight given to the unipolar electrostatic repulsion model compared to the bipolar model (default: 0.2).
- -info display information messages.
- -quiet do not display information messages or progress status. Alternatively, this can be achieved by setting the MRTRIX_QUIET environment variable to a non-empty string.
- -debug display debugging messages.
- -force force overwrite of output files. Caution: Using the same file as input and output might cause unexpected behaviour.
- -nthreads number use this number of threads in multi-threaded applications (set to 0 to disable multi-threading).
- -help display this information page and exit.
- -version display version information and exit.
