Reproducing the results

The results in this paper can be completely reproduced using open-source software and publicly available datasets. We will soon post here the set of workflows needed to run the experiments directly in VisTrails, along with the necessary software.

Alternative #1: Ubuntu repository

If you run Ubuntu Linux, you can simply add our APT repository

deb http://vgc.sci.utah.edu/ubuntu edgy main

and install the package "ectmc" we are currently creating. This will install all the software you need with the right versions, so running the experiments will be a matter of downloading the actual vistrail containing the workflows and running it:

# apt-get install ectmc

Follow these instructions.

Alternative #2: Downloading and using VisTrails manually

You can download all the individual software manually.

Requirements for running the experiments

• VTK Version 5.0 or higher, with Python bindings
• [1] Matplotlib
• [2] Afront

VisTrails packages

(TODO: Finish the text) tarball of all necessary VisTrails packages.

Datasets

The datasets we used are all available on the Volvis website. We use the NRRD toolset to access the data, so you need the NRRD header files to go with the raw volumes. You can get the NRRD headers and dataset we used here.

Vistrail

The vistrail you will need to open is available here. Each version shows a different technique. The topmost one is the one we are proposing (MACET).
