Re: On .pos file format

Here comes another .pos file example showing that the .pos-file-header with meta-data can be almost any length. If you want to read only the X,Y coordinates, you have to use a mechanism which can skip the leading meta data!

On .pos file format

Got a question from Jean-Luc Dupouey about .pos format specification. Here is some basic info. Have you ever opened a dendro .pos file with a text editor like e.g. Notepad++ or Epsilon and compared it with what you see on screen with CooRecorder? Here is some basic info on how points are represented...

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&...
