This is a generic function that converts another object to a
DiffusionScheme by extracting the relevant information. There are
methods for matrices (of gradient directions) and MriImage objects.
An image passed as an argument to the latter must have the bValues
and bVectors tags set appropriately.
asDiffusionScheme(x, ...)# S3 method for matrix
asDiffusionScheme(x, bValues, ...)
# S3 method for MriImage
asDiffusionScheme(x, ...)
# S3 method for DiffusionScheme
asDiffusionScheme(x, ...)
A DiffusionScheme object.
An object to coerce to a DiffusionScheme.
Additional arguments to methods.
A vector of b-values, required when x is a matrix of
gradient directions.
