SuSpect for Mac

From EdGCM:

SuSpect is a tool that is designed for searching and exploring large text-formatted data sets. It can also be used to extract subsets of the data for use in other analysis applications (imaging, plotting, statistics, etc.). SuSpect makes it simple and efficient to compare data sets that reside within one text file, but its real power lies in its capabilities for comparing multiple data files. SuSpect will work with any text-formatted files, but it was specifically designed for use with the standard climate diagnostic output of the NASA/GISS Global Climate Model (GCM).
