In MATLAB, I use write_annotation(fname, v, L, ct) to save an annotation file where: v is a 40962x1 matrix. L is a 40962x1 matrix. ct.table is a 113x5 array. This MATLAB code runs without problems.

In MATLAB, I use write_annotation(fname, v, L, ct) to save an annotation file where:
v is a 40962x1 matrix.
L is a 40962x1 matrix.
ct.table is a 113x5 array.
This MATLAB code runs without problems.
However, in Python, I encountered an error when using FreeSurfer's nibabel.freesurfer.write_annot function. Here is my Python code:
nib.freesurfer.write_annot(fname, labels, ct_table, names)
where:
labels is a 40962x1 array.
ct_table is a 113x5 array.
names is a list of structure names.
