Supplementary Material A: Folder with three folders: Folder1: "octave or matlab executable"; Folder2: "output files", Folder3: "source code"

--1) Folder1: "octave or matlab executable"

Three files:

"dwl_script.m": Script for extracting dominant wavelength in digitalized stylolites.
Steps to reproduce:

1. Read CSV files, with X and Y coordinates;
2. Remove trends by polynomial regression;
3. Spatial grid information;
4. Fabricate new grid by Y-interpolation;
5. Frequency grid;
6. Fast Fourier Transform;
7. Dominant frequency and wavelength;
8. Bandpass filter (Call function Bandpass);
9. Show results.

"Bandpass.m": Apply bandpass filter to the profile f(x), considering the frequency interval [kappa0,kappa1].
Steps to reproduce:

1. Spatial grid information;
2. Frequency grid;
3. Fast Fourier Transform;
4. Multiplication by the filter and inverse transform.

"working_sample_1.csv": Cartesian coordinates of a digitized stylolite.

Dwl script, Bandpass function and "Working_sample_1.csv" must be in the same folder.

--2) Folder2: "output files"

Four output figures:

"figure_1_bandpass_filter.jpg": Results of applying the bandpass filter in the real frequency domain.

"figure_2_stylolite_grid.jpg": Stylolite grid

"figure_3_dwl_final_image.jpg": Comparison between the dominant wavelengths and the digitized stylolite.

--3) Folder3: "source code"

Three files:

"bandpass_filter_source_code.txt"

"dwl_script_source_code.txt"

"working_sample_1.csv": Cartesian coordinates of a digitized stylolite.

Table 1: Stylolites hosted in Calcitic Breccia;
Table 2: Stylolites hosted in Dolomitic Breccia;
Table 3: Stylolites hosted in Calcitic Marble;
Table 4: Stylolites hosted in Metamarl.

"Code and data availability.rar": All code and supplementary materials compressed (.zip).

补充材料A：包含三个子文件夹的总文件夹：
1. 文件夹1："octave或MATLAB可执行文件"
内含3个文件：
- "dwl_script.m"：用于从数字化缝合线中提取主波长的脚本。复现步骤如下：
1. 读取包含X、Y坐标的CSV文件；
2. 通过多项式回归去除趋势项；
3. 获取空间网格信息；
4. 通过Y轴插值生成新网格；
5. 生成频率网格；
6. 快速傅里叶变换（Fast Fourier Transform）；
7. 计算主频率与主波长；
8. 带通滤波（调用Bandpass函数）；
9. 展示结果。
- "Bandpass.m"：针对剖面$f(x)$应用带通滤波器，需指定频率区间$[kappa_0, kappa_1]$。复现步骤如下：
1. 获取空间网格信息；
2. 生成频率网格；
3. 快速傅里叶变换；
4. 与滤波器相乘后进行逆变换。
- "working_sample_1.csv"：一条数字化缝合线的笛卡尔坐标数据。
注意：DWL脚本、Bandpass函数与"working_sample_1.csv"需置于同一文件夹中。
