How to see the year number of a certain ring

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...

Re: The Development version of CDendro

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...

Fooled by the normalization method and some narrow rings

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...

Re: CNRS Database

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...

Re: CNRS Database

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...

Working with Multi-radius samples

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...

The Development version of CDendro

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...
