C3d

Link to code

Wraps the executable command c3d.

Convert3d is a command-line tool for converting 3D (or 4D) images between common file formats. The tool also includes a growing list of commands for image manipulation, such as thresholding and resampling. The tool can also be used to obtain information about image files. More information on Convert3d can be found at: https://sourceforge.net/p/c3d/git/ci/master/tree/doc/c3d.md

Example

>>> from nipype.interfaces.c3 import C3d
>>> c3 = C3d()
>>> c3.inputs.in_file = "T1.nii"
>>> c3.inputs.pix_type = "short"
>>> c3.inputs.out_file = "T1.img"
>>> c3.cmdline
'c3d T1.nii -type short -o T1.img'
>>> c3.inputs.is_4d = True
>>> c3.inputs.in_file = "epi.nii"
>>> c3.inputs.out_file = "epi.img"
>>> c3.cmdline
'c4d epi.nii -type short -o epi.img'

Inputs:

[Mandatory]
in_file: (a list of items which are a file name)
        Input file (wildcard and multiple are supported).
        argument: ``%s``, position: 1

[Optional]
out_file: (a file name)
        Output file of last image on the stack.
        argument: ``-o %s``, position: -1
        mutually_exclusive: out_files
shift: (an integer (int or long) or a float)
        Adds the given constant to every voxel.
        argument: ``-shift %s``
interp: ('Linear' or 'NearestNeighbor' or 'Cubic' or 'Sinc' or
          'Gaussian')
        Specifies the interpolation used with -resample and other commands.
        Default is Linear.
        argument: ``-interpolation %s``
out_files: (a list of items which are a file name)
        Write all images on the convert3d stack as multiple files. Supports
        both list of output files or a pattern for the output filenames
        (using %d substituion).
        argument: ``-oo %s``, position: -1
        mutually_exclusive: out_file
smooth: (a unicode string)
        Applies Gaussian smoothing to the image. The parameter vector
        specifies the standard deviation of the Gaussian kernel.
        argument: ``-smooth %s``
multicomp_split: (a boolean, nipype default value: False)
        Enable reading of multi-component images.
        argument: ``-mcr``, position: 0
pix_type: ('float' or 'char' or 'uchar' or 'short' or 'ushort' or
          'int' or 'uint' or 'double')
        Specifies the pixel type for the output image. By default, images
        are written in floating point (float) format
        argument: ``-type %s``
resample: (a unicode string)
        Resamples the image, keeping the bounding box the same, but changing
        the number of voxels in the image. The dimensions can be specified
        as a percentage, for example to double the number of voxels in each
        direction. The -interpolation flag affects how sampling is
        performed.
        argument: ``-resample %s``
environ: (a dictionary with keys which are a bytes or None or a value
          of class 'str' and with values which are a bytes or None or a
          value of class 'str', nipype default value: {})
        Environment variables
is_4d: (a boolean, nipype default value: False)
        Changes command to support 4D file operations (default is false).
args: (a unicode string)
        Additional parameters to the command
        argument: ``%s``
scale: (an integer (int or long) or a float)
        Multiplies the intensity of each voxel in the last image on the
        stack by the given factor.
        argument: ``-scale %s``

Outputs:

out_files: (a list of items which are a file name)
