Brainvoyager QX tips and tricks 1; Some visualization tips

This entry is part of my talk about advanced features of visualization in Brain Voyage QX which was held in May 2008 at MARIARC, Liverpool.

I used BVQX (1.9.10). There are some differences between different versions, so please take this issue in account if you use another version. Hopefully, this could help!

Before starting; you have to refer to BrainVoyager QX Getting Started Guide
BrainVoyager QX Getting Started Guide

1- Sphere Mapping (Cortex-based alignment)
This can be done faster and easier in an automated way using a script provided through brain voyager QX support site by Draulio de Araujo. However, I am showing the normal method here.

2- Illustration of Brodmann areas, lobes, sulcus and gyruses...(on mesh)
Sphere Mapping should be processed before starting this step. Doing all of the previous steps ending with folding the (...RECOSM.srf) mesh by setting standard sphere vertices (image 7).
You should load a patch of interest from database that located in Atlas Brains folder in Brain voyager QX directory.

3- Illustration of Brodmann areas on 3D view; SAG, COR, AND TRA 
You should download  brodma.voi from Brain voyager user forums. or email me if you want a copy. (This file is available in the newest versions (Brainvoyager QX 2.x.x).

4- Drawing region on a mesh
In the following step, you should use ctrl and mouse click in order to draw a region of interest.When you finish drawing a closed curve you can toggle to fill mode and fill the region.

5- Representation of demarcated region on a polygon mesh
