This freely available open source application is available for Windows, Mac OSX and Linux.For more details see: Brewer, P., Murphy, D., and Jansma, E., 2011 TRi CYCLE: a universal conversion tool for digital tree-ring data. Thanks to Paul Krusic, Ed Cook, and the Tree-Ring Laboratory at Columbia University, the standardization program ARSTAN has been ported over to run on Macintosh OS X and Windows OS computer, and it has the capability to produce high-resolution screen graphics!Some key features include:- User friendly graphical interface- Built upon the Tree Ring Data Standard (TRi Da S)- Import/export support for 22 dendro data formats- Support for standard measuring platforms- Integrated 3D mapping with GPS, WMS, KML and shapefile data import- Barcode-based curation of samples- Relational database server for all data and metadata- Security architecture with fine-grained permission controls Without a doubt, this suite of programs, written by Richard L. Routines are provided to edit tree-ring data, change formats, verify reconstructions, read or create files in spreadsheet formats, and estimate missing climate or tree-ring data.To make downloading an easier process, I provide links directly to the individual zipped files. When you click on one of the links below, a window should open in your browser, asking whether you wish to run the file or save it to your hard disk.It is available for Mac OSX, Windows and Linux from This first release concentrates on measuring, organizing, and curating samples. Krusic, has had a great impact on the way the dendrochronological community analyzes tree-ring data.For years, the tree-ring lab at Columbia University has been at the forefront of producing high-quality and comprehensive programs for use by dendrochronologists, thanks to Ed Cook and Paul Krusic, especially.To further make these useful, they offer all programs in both OSX (for MACS) and Windows (for PCs) versions.

You will need teh latest version of COFECHA, however (6.06 or later, downloadable from above).Bootstrapping is performed to ensure robust estimates of confidence intervals.Input data required are monthly temperature and precipitation data as well as the tree-ring index chronology.The programs are too numerous to list individually here but connect to this web site and you'll see programs that are also able to extract and retrieve gridded climate data at various resolutions.You'll also find very useful programs not normally found in other dendro programs, such as routines to seasonalize climate data, conduct principle components regression, even plot and edit tree-ring data!

The package contains customizable functions to prepare, verify, process and plot dendrometer series, as well as functions that facilitate the analysis of dendrometer data (i.e.
