Documentation on CDendro & CooRecorder

I have recently updated several sections at http://www.cybis.se/forfun/dendro . There is now also a new section http://www.cybis.se/forfun/dendro/detrendandnormalize/index.htm on Detrending, Normalization, Discrimination and Autocorrelation. Edit April 2016: For CooRecorder bluechannel information, ...

On calculating bark widths separately for later processing

Got this: Hi Lars-Ake, I have a problem with some .pos files that I have created, and I wondered if you would be able to give me some advice. I have a dataset of approximately 3600 cores, which I wanted to analyse using basal area increment. I measured the cores, and I have created chronologies usin...

How to use CDendro: Skeleton plotting

A few users have had a problem with finding out how to activate the skeleton plotting mechanisms in CDendro. Under the heading "Using CDendro:" in the left column of http://www.cybis.se/forfun/dendro there is now a new section "6. A demo with skeleton plotting". Here is a direct ...

Re: Removing non-zero rings

Recently I got the question below which is somewhat related to the subject of this thread. When adding mutliple zero-rings, it appears there is a limit to how close together they can be added. For example, if I insert a zero-ring at ring number 15, the next "individual" (for lack of a bett...

How to measure only the five outer rings?

Today I got a question on how to measure only the five outer rings of a number of samples. Measuring just exactly not more than five rings is a very special case that nobody else has asked me for! I understood that the questioner had tried it and found that it does not work in CDendro! That is becau...

Re: Removing non-zero rings

Within the TEST version of CDendro 7.5 there is now a mechanism for removing a non-zero ring. There is already a mechanism for inserting a zero-ring (right-click on the curve) and for removing a zero ring (shift-right-click on the zero ring on the curve). When there is no zero ring, then a shift-rig...

Re: Removing non-zero rings - .POS files

When it comes to removing rings originating from a .pos file, the case is much easier: Note the ring number in CDendro. That number is also normally shown in CooRecorder. So alt-tab to your CooRecorder session and update your measurements and save the file again (with the same name). Then alt-tab to...

Re: Removing non-zero rings

It happens often that I find an extra inserted ring in one of the series and I need to remove it before adding it to the target collection. Is there an efficient way of doing this? Right now I crop the series into two parts (leaving out the extra ring), I then save each part as a .wid, than I reimp...

Re: Mersea chronology (AD 445-661) - England

While searching the web for roman pines chronologies (impossible!), I quickly retrieved an oak chronology from Crummy P., Hillam J., Crossan C. 1982, Mersea Island: the Anglo-Saxon causeway, in Essex Archaeology and History, 14, pp. 77-86 (http://cat.essex.ac.uk/reports/EAS-report-0023.pdf).

CooRecorder does not display numbers any longer, why?

Question: ...my copy of coorecorder recently stopped showing numbers associated with ring width measurments. That is, I click on the ring, and the appropriate + mark appears, but there is no number with it. The crack markers, and the two markers per ring function also do not have any numbers. Any s...
