Alternate short alias for mp_pca4d

Usage

mppca4d(
  vec,
  patch = c(5L, 5L, 5L),
  tw = 32L,
  stride = c(3L, 3L, 3L, 8L),
  sigma_mode = c("patch", "global", "fixed"),
  sigma_value = NULL,
  mask = NULL
)

Arguments

vec: 4D fMRI array or `NeuroVec`.
patch: Integer length-3 patch size (voxels).
tw: Temporal window size (frames).
stride: Integer length-4 stride for x,y,z,t.
sigma_mode: Noise mode: 'patch' (estimate per-patch), 'global' (one value), or 'fixed'.
sigma_value: Noise sigma when `sigma_mode='fixed'`.
mask: Optional 3D logical/0-1 mask.
