Hi, thanks for the great videos. I am trying to teach myself Dendrochronology, but have no background in that field. If you have a sample but you do not know where it came from, how do you go about the process of finding the correct Master Chronology? Im struggling to understand this first part. Would you plot the tree rings in Coorecoder without the Master reference and then bring the file into Cdendro and import the .rwl files from the ITRDB and try to cross match it? Then if you find a good correlation would you create a Master Chronology .wid file and use that and go back into the Coorecorder process? For example, if you were pretty sure that the wood was European and from Germany would you just import the relevant .rwl files from Germany and look for a correlation? Sorry for the stupid questions, im just a bit confused about what to do if you have an unknown sample and can't find and videos that explain this. Thanks in advance.
Excellent tutorial, thank you very much for producing it for all of us! Question, I have found that sometimes when I go to add a ring boundary that didn't get picked up in the first auto placing pass, the ring sometimes gets labeled as the next successive ring after the oldest (inner ring). Is there a way to manually assign the proper year?
Great tutorial. I couldn't help but notice that year 18 wasn't quite on the ring. Would this cause an error in cross-dating it to your master chronology or would the error be so small that it wouldn't be significant?
Ring boundaries should be accurately placed. Normally, I check each sample for boundary placement to minimize measurement errors. The small difference in placement would likely not cause an error in crossdating. However, you should always go back to the wood to verify measurements and dating!
At www.cybis.se/forfun/dendro/helpcoorecorder7 you will find a section "How to measure at right angles or over a crack" or www.cybis.se/forfun/dendro/helpcoorecorder7/meacrack where there is a description about "the crack marker tool" which is used to insert two points around a crack to exclude that distance from the ring width.
See that you are in D-mode (data picking mode). Then just click on the point where you want your new ring. There are quite exensive help texts at www.cybis.se/forfun/dendro/helpcoorecorder7/index.php
up to date, this is really hepful and am glad you put up this information Dr. stockton
Outstanding tutorial. Right enough info to do the job. I've compiled one myself, but this one is way better. I recommend this to my students.
Thank you very much, I did not know this software. It will be very useful to me.
thank you for this tutorial! wher can i find databank for european wood?

I have found that erasing a group of preceding points and then remeasuring does seem to restore proper numbering.
Great tutorial. That's exactly what I need :)

Can you also make a tutorial video about Blue Intensity (BI) analysis with Coorecorder ? It would be really helpful.
Probably this summer
Not a video, but please anyhow see this extensive example:

@@lars-akelarsson6772 It is really helpful, thank you.
Good evening can help me in reading the rings in the picture (took2022)
How about the gap in the middle of ring?
At www.cybis.se/forfun/dendro/helpcoorecorder7 you will find a section
"How to measure at right angles or over a crack"
or www.cybis.se/forfun/dendro/helpcoorecorder7/meacrack
where there is a description about "the crack marker tool" which is used to insert two
points around a crack to exclude that distance from the ring width.
How to mark a ring when I miss it during AutoPlace?

I plan to get to some more Coorecorder videos soon. I'll put that on the last.
