manual page for usage: tff_manipulate_datatype [-h]

Description

usage: tff_manipulate_datatype [-h]

[--positions_dtype {float16,float32,float64}]

[--offsets_dtype {uint32,uint64}] [--dpv NAME DTYPE] [--dps NAME DTYPE] [--groups NAME DTYPE] [--dpg GROUP NAME DTYPE] [-f] in_tractogram out_tractogram

Manipulate a TRX file internal array to change their data type.

Each instance of --dps, --dpv, --groups require 2 arguments (FILE, DTYPE). --dpg requires 3 arguments (GROUP, FILE, DTYPE). The choice of DTYPE are:

- (u)int8, (u)int16, (u)int32, (u)int64 - float16, float32, float64 - bool

Example command: tff_manipulate_datatype.py input.trx output.trx     --position float16 --offsets uint64     --dpv color_x uint8 --dpv color_y uint8 --dpv color_z uint8     --dpv fa float16 --dps algo uint8 --dps clusters_QB uint16     --dps commit_colors uint8 --dps commit_weights float16     --group CC uint64 --dpg CC mean_fa float64

positional arguments

in_tractogram

Input TRX file.

out_tractogram

Output filename. Format must be one of trk, tck, vtk, fib, dpy, trx.

options

-h,  --help

show this help message and exit

-f

Force overwriting of the output files.

Data type options

--positions_dtype {float16,float32,float64}

Specify the datatype for positions for trx. [float16, float32, float64]

--offsets_dtype {uint32,uint64}

Specify the datatype for offsets for trx. [uint32, uint64]

Streamlines metadata options

--dpv NAME DTYPE

Specify the datatype for a specific data_per_vertex.

--dps NAME DTYPE

Specify the datatype for a specific data_per_streamline.

--groups NAME DTYPE

Specify the datatype for a specific group.

--dpg GROUP NAME DTYPE

Specify the datatype for a specific data_per_group.
