diffViz
To highlight the differences in an easy-to-understand manner, diffViz visually separates the common and different blocks of a pair of pre-processed traces (or any pair of text-based files) by implementing the diff algorithm. diff takes two sequences A and B and computes the minimal edit to convert A to B. This algorithm is used in the GNU diff utility to compare two text files and in git for efficiently keeping track of file changes. diffViz aligns common and different blocks of a pair of sequences (e.g., traces) horizontally and vertically, making it easier for the analyst to see the differences at a glance.
diffViz is now available from this Github repository.
