Create a simple smoothing transformer

This creates a transformer function that adds a smoothing description to BIDS filenames. This is a lightweight example - real implementations would perform actual image processing.

Usage

create_smooth_transformer(fwhm, suffix_pattern = "bold\\.nii")

Arguments

fwhm

The smoothing FWHM to add to the description.

suffix_pattern

Optional regex pattern to match specific file types.

Value

A transformer function for use with bids_transform.

Examples

# \donttest{
# Create a smoothing transformer
smooth_6mm <- create_smooth_transformer(6)

# Use with bids_transform (example)
# ds_path <- get_example_bids_dataset("ds001")
# proj <- bids_project(ds_path)
# new_files <- bids_transform(proj, smooth_6mm, "smoothed", 
#                             subid = "01", suffix = "bold.nii.gz")
# }
