John Readey, The HDF Group   We’ve recently announced a new viewer application for HDF5 files: HDF Compass.

HDF Compass is a desktop viewer application for HDF5 and other file formats. A free and open source software product, it runs on Mac OS X, Windows, and Linux.   Compass was initially developed by Andrew Collette, a Research Scientist with IMPACT (Institute for Modeling Plasma, Atmospheres and Cosmic Dust).  He has decided to work with The HDF Group to further the development of Compass. Andrew has written a very interesting blog that goes into some of the background of Compass and...

Lindsay Powers - The HDF Group The HDF Group provides free, open-source software that is widely used in government, academia and industry.

Today, it is an expression of hope for the spreadsheet users who run this country and who either felt neglected by the HDF5 community or who might suffer from a medical condition known as data-bulging workbook stress disorder. In this article, I would like to give you a quick overview of the novel PyHexad therapy and invite you to get involved (after consulting with your doctor).

To access the data in HDF5 files from Excel is a frontrunner among the all-time TOP 10 most frequently asked for features. A spreadsheet tool might be a convenient window into, and user interface for, certain data stored in HDF5 files. Such a tool could help overcome Excel storage and performance limitations, and allow data to be freely “shuttled” between worksheets and HDF5 data containers. PyHexad ([4],[5],[6],[7]) is an attempt to further explore this concept.
