       tff_manipulate_datatype.py - manipulate TRX file array to change data type

DESCRIPTION

       usage: tff_manipulate_datatype.py [-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.
