Why read_time_series_data failed for "naming_functions"?

[hongbo-miao]

I am using miss-hit 0.9.42

I have a function function [xyz, ptp] = read_time_series_data(varargin) in the file read_time_series_data.m.

However, I got error

In read_time_series_data.m, line 1
| function [xyz, ptp] = read_time_series_data(varargin)
|                       ^^^^^^^^^^^^^^^^^^^^^ style: violates naming scheme for function [naming_functions]
MISS_HIT Style Summary: 5 file(s) analysed, 1 style issue(s)

Based on "naming_functions" section in the https://florianschanda.github.io/miss_hit/style_checker.html

read_time_series_data does seem following the regex "[a-z]+(_[a-z]+)*".

Any ideas? Thanks!
