Analysing data where spreadsheets fear to tread
For any engineer or researcher working with long time series, DADiSP has long represented an intriguing third way of manipulating, editing, displaying or analysing data. The latest release, DADiSP/2002, available from Adept Scientific, contains a number of interesting developments, making it an even more powerful tool for analysing large data sets.
DADiSP acquires, reads and even generates data, displaying the results in multiple windows for immediate graphic comparison. A DADiSP worksheet is comprised of as many analysis windows as are required, each of which can contain either graphs or tables of raw data, or data transformed by one of DADiSP’s many analysis functions. The data and graphs in each DADiSP window can be related through formulae to those in other windows, enabling an analysis chain to be created without programming. When new data is loaded into the raw data windows, dependent analysis windows automatically recalculate and update, graphically.
The new DADiSP/2002 supports external Worksheet Documents or .DWK files (DADiSP Worksheet File). DWK files are single file, standalone worksheets that can be saved or opened by DADiSP. The program also functions as a full ActiveX Document Server. DADiSP Worksheets can be embedded, manipulated, saved and printed by any ActiveX Container application such as MS Excel or MS Word.
DADiSP/2002 employs an optimised memory management scheme to make the most of system memory when processing large or small datasets. Large series are transparently buffered to and from the disk while in memory buffers are sized specifically to the result of the calculation at hand. The maximum buffer size can be customised to take advantage of today’s large memory systems. Calculations involving smaller series are automatically compacted to conserve total memory space.
DADiSP/2002 includes over 80 new built-in and SPL routines spanning the areas of matrix and series manipulation, signal processing, maths, colour, series generation, curve fitting and statistics. It now offers over 1000 analysis routines with an intuitive and familiar user interface to provide one of the most complete and easy to use data analysis tools available today.

What do our Customers say about us?
At 13-years old, my daughter’s research manuscript has been accepted for publication in a top tier peer-reviewed Environmental Science journal and OriginPro 8.6 will allow her to export the graphs in a wide variety of formats which can meet any publisher’s requirements. Kudos to OriginLab for designing innovative and intuitive software that can span the needs of both a burgeoning young scientist like my daughter to a PhD expert in their field. It is hard to imagine that other products offer this extraordinary level of user versatility.Michael Grimmett, MD, FACP, FACS Ophthalmologist Palm Beach Gardens, Florida
“Origin has always been one of the most powerful packages for data analysis and graphing. With the new multi-sheet workbook’s full formatting features and its ability to embed both images and graphs, OriginLab is moving a big step forward. From raw data to final professional report creation, you can now keep all the stages of data processing in a single software.”Antoine Couturier, Ph.D. - Service Recherche, Institut National du Sport, de l'Expertise et de la Performance
