invert_xfm(inmat, omat = tempfile(fileext = ".mat"), verbose = TRUE)

concat_xfm(inmat, inmat2, omat = tempfile(fileext = ".mat"), verbose = TRUE)

fixscaleskew_xfm(
  inmat,
  inmat2,
  omat = tempfile(fileext = ".mat"),
  verbose = TRUE
)

Arguments

inmat

input matrix transformation
omat

output matrix transformation

print diagnostic messages
inmat2

second matrix filename to be concatenated or fixscaleskew to first

Value

Examples

if (have_fsl()) {
img = mni_fname()
mat = fslreorient2std_mat(img)
inverted = invert_xfm(mat)
readLines(inverted)
catted = concat_xfm(mat, mat)
readLines(catted)
fixed = fixscaleskew_xfm(mat, mat)
readLines(fixed)
