FWHMx brick¶

Computes FWHMs using AFNI FWHMx¶

This brick computes FWHMs for all sub-bricks (3D volumes for each TR) in the input dataset, each one separately.

Mandatory inputs parameters:

in_file (a string representing an existing file)

Input image.

ex. '/home/username/data/derived_data/mean_reg_func_valid.nii'

Optional inputs with default value parameters:

combine (a boolean, optional, default value is True)
Combine the final measurements along each axis.
ex. True
detrend (a boolean or an integer, optional, default value is True)
Detrend to the specified order.
ex. True
out_prefix (a string, optional, default value is ‘fwhm’)
Specify the string to be prepended to the filename of the output file.
ex. 'fwhm_'

Optional inputs:

args (a string representing an existing file, optional)
Add an option as ‘-ShowMeClassicFWHM’ (use old classic method to compute FWHM)
ex. '-ShowMeClassicFWHM'

mask_file (a string representing an existing file, optional)

Mask image.

ex. '/home/username/data/derived_data/automask_mean_reg_func_valid.nii'

Outputs parameters:

out_file (a strings representing a file)

Out file.

ex. '/home/username/data/derived_data/fwhm_mean_reg_func_valid.out'
