sct_dmri_concat_bvecs

Concatenate bvec files in time. You can either use bvecs in lines or columns. N.B.: Return bvecs in lines. If you need it in columns, please use sct_dmri_transpose_bvecs afterwards.

usage: sct_dmri_concat_bvecs -i <file> [<file> ...] [-o <file>] [-h] [-v <int>]
                             [-profile-time [<file>]] [-trace-memory [<folder>]]

MANDATORY ARGUMENTS

-i

List of the bvec files to concatenate. Example: dmri_b700.bvec dmri_b2000.bvec

OPTIONAL ARGUMENTS

-o

Output file with bvecs concatenated. Example: dmri_b700_b2000_concat.bvec

MISC ARGUMENTS

-v

Possible choices: 0, 1, 2

Verbosity. 0: Display only errors/warnings, 1: Errors/warnings + info messages, 2: Debug mode.

Default: 1

-profile-time

Enables time-based profiling of the program, dumping the results to the specified file.

If no file is specified, human-readable results are placed into a ‘time_profiling_results.txt’ document in the current directory (’/home/docs/checkouts/readthedocs.org/user_builds/spinalcordtoolbox/checkouts/stable/documentation/source’). If the specified file is a .prof file, the file will instead be in binary format, ready for use with common post-profiler utilities (such as snakeviz).

-trace-memory

Enables memory tracing of the program.

When active, a measure of the peak memory (in KiB) will be output to the file peak_memory.txt. Optionally, developers can also modify the SCT code to add additional snapshot_memory() calls. These calls will ‘snapshot’ the memory usage at that moment, saving the memory trace at that point into a second file (memory_snapshots.txt).

By default, both outputs will be placed in the current directory (’/home/docs/checkouts/readthedocs.org/user_builds/spinalcordtoolbox/checkouts/stable/documentation/source’). Optionally, you may provide an alternative directory (-trace-memory <dir_name>), in which case all files will be placed in that directory instead. Note that this WILL incur an overhead to runtime, so it is generally advised that you do not run this in conjunction with the time profiler or in time-sensitive contexts.
