This is how the heavy detrended (green) version of 6680NY matches towards the original raw ring width version (blue).

Re: Questions related to the dendroecology class

This wid file is sorted from the sample date backwards from top to bottom, right? Right! The youngest ring widths of a .wid file are at the beginning of the file - or top of the column if you like to say so. It is the same with CooRecorder: You have to start setting coordinate points from the outsi...

Re: Questions related to the dendroecology class

1) how could I get the detrended series out of CDendro. Open any saved collection with your raw ring width data. (I had Swed302Namdo.rwl) For your later testing: Open (double click) any member (I had 6680NY) and select it as your reference. Go back to your collection: See that you have selected the...

Re: Questions related to the dendroecology class

Lars-Åke, do you know any means by how we might run CooRecorder/CDendro on macOS? I know that LINUX users may use WINE as a windows simulator, which works fine with the software. Top A few years ago ryszardjkaczka@gmail.com demonstrated CooRecorder running on his Mac. I THINK that he had a Windows ...

Re: Measuring Latewood and Earlywood

Just found out that there are already mechanisms to export latewood or earlywood from a collection consisting of "seasonwood-.pos-files". Use the command Collections/Save late and earlywood.../Write latewood andalso /write earlywood. There is also a special variant of the .rwl format which...

Measuring Latewood and Earlywood

have a question regarding Earlywood and Latewood (EW, LW) which I cannot solve, although I found the topic and some instructions on the web pages of the program. The questions are: (1) If we measure RW and create a *pos file which is dated by manually inserting the End Year. Is it later possible to...

Re: How to account for reversed segment

Another way to handle a reversed segment might be to use an image editor and rotate that wrongly mounted section within the image. Or make a copy of that segment, rotate it and "mount" it in parallel with the original image. Then when measuring in CooRecorder, you use a "double point&...

Re: How to account for reversed segment

I have a core, already glued down and sanded, in which there is a segment about 10 rings long that is reversed. Is there any way to deal with this in CooRecorder or CDendro? Hello Seth, CooRecorder is written to sort your measurement points from the start point (i.e. youngest ring at index 0) and o...

Re: Big images can be opended on 64 bit machines.

Just found out that a 9800 by 18000 pixels .tif image stored as 520 MB on my disc can easily be opened in CooRecorder on Petra's 64 bit machine running Windows 7 with 6 GB memory installed. So it seems that the CooRecorder's memory problem has been much released when using a modern 64 bit Windows ma...
