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 proper detrending method at "DeTrending for ring width curve"
Then use the command Collections/Save as new collection with detrended members/.../as Heidelberg formatted file
and save your new collection as e.g. Swed302NamdoHeavyDetrend.fh (there is another command for rwl saving)
Then open that .fh file and double click the new version of 6680NY. Look at the green/blue curves in the lower part of the curve diagram.
See that the checkbox Ind.ring-w scaling" IS UNCHECKED. so that you have the same scaling of your curves.
The blue curve represents the original raw ring widths, the green curve is the detrended version.
You can now export your version of Swed302NamdoHeavyDetrend.fh using the various export mechanisms.
