Software

TRL scientists strongly support the sharing of specialized software for the growth and benefit of the tree-ring community. It has been our experience that the best advances made in the discipline have come from the free exchange of ideas and knowledge which are often incorporated in the programs we routinely use .

Dendrochronology is a computationally intensive discipline. As more difficult questions are asked of our data the need for more specialized software becomes apparent. The programs offered here are continually updated or revised reflecting our commitment to advancing tree-ring research.

Disclaimer: Nearly all programs provided here are the intellectual property of the Tree-Ring Lab (TRL) and Columbia University.  You are welcome to use them and give them to others.  The TRL and Columbia University are not responsible for what you do with these programs and will not make any claim for or against results from experiments you perform with them.  At the same time we are not responsible for the training or support of these programs.  We suggest using the International Tree-Ring Data Base Forum (ITRDBFOR) for all questions. 

Note: Off and on from May to August this year we will be updating many of our old programs and adding some new ones.  Please be patient with us during this period.  If there is a link that does not work, or a program you would like to see returned to the list, send an email to pjk@ldeo.columbia.
