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...

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...

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...
