Pipeline for Generating Brain Surface Mapping Files This repository contains the pipeline and resources for generating .curv brain mapping files for cortical surface visualization using FreeSurfer.

Contents Data_input_for_creating_curv_mapping_file.xlsx main_function.m fwrite3.m write_curv.m Fig_2a_left.curv, Fig_2a_right.curv, Fig_2b_left.curv, Fig_2b_middle.curv, Fig_2b_right.curv Fig_S5a.curv, Fig_S5b.curv

1️⃣ Environment Server: XXX (please specify your server model) Operating System: XXXX Software Dependencies: MATLAB 2018b FreeSurfer v7.1.1 Freeview (FreeSurfer visualization tool)

2️⃣ Generate .curv Files 2.1 Input Data_input_for_creating_curv_mapping_file.xlsx: Source values to be mapped onto cortical surfaces. 2.2 Code Files main_function.m: Main script for generating .curv files. fwrite3.m: Helper function for binary writing. write_curv.m: Writes data to FreeSurfer .curv format.

3️⃣ Visualization Using Freeview (e.g., for Figure 2a & 2b) 需要图 3.1 Figure 2a (Right Three Panels) Open Freeview File → Load Surface → rh.pial_semi_inflated Overlay → Load Generic → Fig_2a_right.curv Overlay → Configure Adjust colorbar Choose Right view, Inferior view, Left view as needed

3.2 Figure 2b (Right Two Panels) File → Load Surface → rh.pial_semi_inflated Overlay → Load Generic → Fig_2b_right.curv Overlay → Configure Adjust colorbar Choose Right view, Inferior view

4️⃣ Output: .curv Files 4.1 Figure 2a Left panel: Fig_2a_left.curv Right panels: Fig_2a_right.curv

4.2 Figure 2b Left panel: Fig_2b_left.curv Middle panel: Fig_2b_middle.curv Right two panels: Fig_2b_right.curv

4.3 Supplementary Figure 5 Left panel: Fig_S5a.curv Right panel: Fig_S5b.curv

Notes Ensure hemisphere (lh or rh) and inflated surface (pial_semi_inflated) match the mapping files.
