GPASub | R Documentation |
Perform functional alignment of a matrix by von Mises Fisher Procrustes model with known reference matrix.
GPASub(
X,
Q = NULL,
k,
ref_ds,
scaling = TRUE,
reflection = TRUE,
centered = TRUE
)
X |
data, i.e., matrix with dimension time points - voxels. |
Q |
value of the location parameter of the prior distribution. It has dimension voxels x voxels, it could be not symmetric. |
k |
value of the concentration parameter of the prior distribution of the rotation parameter. |
ref_ds |
reference matrix to align. |
scaling |
Flag to apply scaling transformation. |
reflection |
Flag to apply reflection transformation. |
centered |
centered data? |
GPASub
returns a list with two components:
Xest |
the aligned matrix |
R |
the rotation matrix |
