In response to a request from Igor Drobyshev, there is now a mechanism which makes it possible to see the corresponding year number for a certain ring. This is useful when you know of some pointer years - known to be related to very thin or very wide rings - and you want to see which rings they corr...

Here is a short preliminary description of the Besancon corridor method:

There is now still another new development version of CDendro - this time named CDendro 7.2 - available for download and testing. Various detrending and normalization methods have been added to the program during a long time. I have now rewritten these methods so they are all handled in the same way...

While analyzing the data in the file CO20050101-LCE-AjC.txt at the French CNRS database I observed a number of quite high Baillie/Pilcher and Hollstein based TTest correlation values which were not considered as correct datings. An analysis revealed that it was caused by a combination of VERY narrow...

Hi Ale and everybody! I've now looked into the Besancon files again. I think I can program a read-in mechanism for these files without getting further information. Of course it would be fine to know more, though many examples are usually the best way to go. About Becanson normalization: The filter o...

Thanks Ale! This is indeed interesting data. I think that it is all oak of some type. The format is quite new to me and I have to write some sort of input filter for CDendro. Though I would be happy if I knew more about the format! The data with negative values are probably based on the "Besanc...

When you have measured several radii from the same tree you can put your samples into a separate collection for that tree. Before you click the "Create mean value sample" button, see that you have checked the proper radiobutton for detrending! E.g. if you want a pure mean value curve witho...

There is now a new CDendro Development version available for testing. It is dated March 19 2009. The main feature is the Besancon index E algorithm now available as one of the main normalization algorithms used for plotting, like Proportion of last two years growth, Hollstein and Baillie/Pilcher. Th...

http://www.cybis.se/forumimages/bapi2.gif Question: Are the indicated fields above signs of an error in CDendro? Why these differences? In this case, the normalized data of the reference has been calculated as mean values from normalized data of all members of a collection. The sample 6680NY has th...

The AutoPlace mode is now improved. When you have set the start point, a thin line will connect that point with your cursor to make it easier to see where to set the end point. A perpendicular line is also drawn which should be parallel with the tree rings at the best position. ----- Sort of a rule...
