# tri2brainstorm

## (Toolbox/tri2brainstorm.m in BrainStorm 2.0 (Alpha))

### Function Synopsis

    [Vertices,Faces, Comments] = tri2brainstorm(TRIFILES, VERBOSE);

### Help Text

    TRI2BRAINSTORM - Read .tri file into BrainStorm format
     function [Vertices,Faces, Comments] = tri2brainstorm(TRIFILES, VERBOSE);
     Reads the .tri files specified in the cell array TRIFILES and outputs
     Vertices, Faces and Comments which are ready to be saved in a BrainStorm Tessellation file.
     VERBOSE toggles the verbose mode (1 is on)

### Cross-Reference Information

This function is called by

    subject_editor                     C:\BrainStorm_2001\Toolbox\subject_editor.m
