as_ieegio_transform: Convert to ieegio transform

Description

Generic function to convert various objects into ieegio_transforms.

Usage

as_ieegio_transform(x, ...)
# S3 method for `NULL`
as_ieegio_transform(x, space_from = "", space_to = "", ...)
# S3 method for character
as_ieegio_transform(x, format = c("ants", "flirt"), ...)
# S3 method for matrix
as_ieegio_transform(x, space_from = "", space_to = "", ...)
# S3 method for array
as_ieegio_transform(x, space_from = "", space_to = "", ...)
# S3 method for list
as_ieegio_transform(x, ...)
# S3 method for ieegio_transforms
as_ieegio_transform(x, ...)

Value

An ieegio_transforms object

Arguments

x: object to convert (character path, matrix, array, list, or existing transform)
...: additional arguments passed to methods
space_from: source space for matrix/array methods. Default "" is a wildcard for arbitrary space name.
space_to: target space for matrix/array methods. Default "" is a wildcard for arbitrary space name.
format: character string specifying the file format for character paths. Supports "ants" (default) for ANTs format and "flirt" for FSL FLIRT format. Only used for character method.

Details

Methods available:

character: Reads transform from file (uses io_read_ants_transform or io_read_flirt_transform depending on format)
matrix: Creates transform from matrix
array: Creates transform from 2D array
list: Creates transform chain from list of transforms
ieegio_transforms: Returns input unchanged
