Takes values and maps them to the correct triangles in space.
gifti_map_value(
pointset,
triangle,
values,
indices = seq(nrow(pointset)),
add_one = TRUE
)A list of coordinates (in triangles) and the corresponding value mapped to those triangles
pointset from GIFTI
triangles from GIFTI
Values to map to the triangles. Same length as indices
indices to place the values, must be in the range of 1 and
the number of rows of pointset
Should 1 be added to the indices for the triangle?
