Extract a colortable lookup table (LUT) from an annotation. Such a LUT can also be read from files like ‘FREESURFER_HOME/FreeSurferColorLUT.txt' or saved as a file, check the ’See Also' section below.

1	colortable.from.annot(annot, compute_colorcode = FALSE)

`annot`	An annotation, as returned by `read.fs.annot`. If you want to assign specific indices, you can add a column named 'struct_index' to the data.frame `annot$colortable_df`. If there is no such columns, the indices will be created automatically in the order of the regions, starting at zero.
`compute_colorcode`	logical, indicates whether the unique color codes should be computed and added to the returned data.frame as an extra integer column named 'code'. Defaults to FALSE.

the colortable data.frame extracted from the annotation.
