DCM Model Renderer

I have added a simple DCM model renderer script called dcm2dot to my SPM Hacks page. With this function DCM model files (DCMxxx.mat) will be analysed and their network written out as Graphviz .dot files. You then can use graphviz small programs like dot to render the network to PNG, PDF, SVG, etc.
Here a simple example of a V1-MT+ DCM:
