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...

Re: Questions related to the dendroecology class
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: 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...

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...

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...
