)

Arguments

vec: 4D fMRI array or `NeuroVec`.
lambda_s: Spatial TV weight.
lambda_t: Temporal TV weight.
loss: Robust loss: `'huber'` or `'tukey'`.
delta: Huber threshold; if `NULL`, derived from noise.
cthresh: Tukey threshold; if `NULL`, derived from noise.
alpha: Tukey shape parameter.
temporal_weights: Optional length-(T or T-1) temporal edge weights.
motion_params: Optional motion regressors to derive temporal weights.
sigma_m: Motion weight scale.
iters: Iterations for the robust solver.
mask: Optional 3D logical/0-1 mask.
tau: Algorithm primal step size; if `NULL`, a sensible default is used.
sigma: Algorithm dual step size; if `NULL`, a sensible default is used.
theta: Over-relaxation parameter.
