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.

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.
