dipy_median_otsu¶
- usage: dipy_median_otsu [-h] [–save_masked] [–median_radius int]
[–numpass int] [–autocrop] [–vol_idx [int [int …]]] [–dilate int] [–out_dir str] [–out_mask str] [–out_masked str] input_files
Workflow wrapping the median_otsu segmentation method.
Applies median_otsu segmentation on each file found by ‘globing’ input_files
and saves the results in a directory specified by out_dir
.
- positional arguments:
input_files Path to the input volumes. This path may contain wildcards to process multiple inputs at once.
- optional arguments:
- -h, --help
show this help message and exit
- --save_masked
Save mask
- --median_radius int
Radius (in voxels) of the applied median filter (default 2)
- --numpass int
Number of pass of the median filter (default 5)
- --autocrop
If True, the masked input_volumes will also be cropped using the bounding box defined by the masked data. For example, if diffusion images are of 1x1x1 (mm^3) or higher resolution auto-cropping could reduce their size in memory and speed up some of the analysis. (default False)
- –vol_idx [int [int …]]
1D array representing indices of
axis=-1
of a 4D input_volume. From the command line use something like 3 4 5 6. From script use something like [3, 4, 5, 6]. This input is required for 4D volumes.
- --dilate int
number of iterations for binary dilation (default ‘None’)
- output arguments(optional):
- --out_dir str
Output directory (default input file directory)
- --out_mask str
Name of the mask volume to be saved (default ‘brain_mask.nii.gz’)
- --out_masked str
Name of the masked volume to be saved (default ‘dwi_masked.nii.gz’)
