## NAME

nipy\_3dto4d - Read 3D image files and write a 4D file

## DESCRIPTION

usage: nipy\_3dto4d \[-h\] \[--out-4d OUT\_4D\] \[--check-affines CHECK\_AFFINES\]

-

  in\_filenames \[in\_filenames ...\]

Read 3D image files and write a 4D file

### positional arguments:

- in\_filenames

  3D image filenames

### optional arguments:

- **-h**, **--help**

  show this help message and exit

- **--out-4d** OUT\_4D

  4D output image name

- **--check-affines** CHECK\_AFFINES

  False if you want to ignore differences in affines between the 3D images, True if you want to raise an error for significant differences (default is True)

nipy\_3dto4d will take a series of 3D nifti images in any format readable by nibabel and concatenate them into a 4D image, and write the image with format guessed from the output image filename. You can set the filename with the \`\`--out-4d\`\` parameter, or we make a filename from the input names.
