Features described:

An Erase command in CooRecorder to erase many points in one operation.
Trim a CooRecorder .pos file from CDendro!
Diagram to point translationGo from a point in a CDendro curve diagram to the corresponding point in the CooRecorder image pane.
Font setting commands make for more legible points and notes in CooRecorder images.
Several growth curves can be plotted in parallel in CDendro.
.rwl files can be written in units of 0.001 mm (not only the common 0.01).
The comments box in CooRecorder can be made pop up automatically when you start measuring a new sample.

Translate diagram data to coordinate data - find the point to add or remove

Clicking on a point in a diagram will print coordinates, ring number and year of that point when the origin is a .pos file.
This saves you time when you want to remove or add a point at a certain place in a coordinate file!

There are always situations of "is this a false ring?" when you are in doubt if a border is a yearly full growth season ring or just a ring probably created by early cold weather in late summer followed by a long period of warm weather. When crossdating you have to add or remove (or enable or disable) such points in CooRecorder. With this "diagram-to-coordinate-data-translation" feature you can quickly go from a curve point in the CDendro curve diagram to a measured point in the CooRecorder measurement pane.

Checking the correlation for a segment of the curve. Cutting off part of a curve/Trimming

You may indicate the start (1) and end (2) of a segment of a longer curve and get the correlation value for that segment calculated (3).

That marked-out part of the sample can be copied (4) into a new sample window.
This may be a quick way to remove a mismatching end of a sample.

How to trim a coordinate file?

Create sample from block
How to write out a truncated (trimmed) sample
When Create a sample from block (i.e. copy a segment) is done on a coordinate file, the original coordinate information is also copied.
So a new coordinate file can easily be written out from that copied data (Samples/Save coordinate data as)!
That is fine when you want to keep only a segment of a coordinate file because of bad crossdating.

How to limit the range (time span) of your current reference curve?
A block created from a "Mean value sample" of a collection can be written out with all data (Samples/Save normalized data as).
That way you can limit the time-span of your reference data when you are crossdating some related very short samples.
And you avoid proposals to crossdate those samples to the reference some 200 years away from where you actually are!

Collections:

Members of a collection can be plotted as parallell curves.
Vertical dated lines can be set on the diagram - just click where you want it.
Click again on a line to remove it!
Both ring width curves and normalized curves can be plotted in this diagram.

The checking status of members can be saved with the collection

Collections can be saved either with only checked members or with all members but with the checking status preserved. This gives you a way to save your job e.g. before you are ready with it.

Invert member checking in a collection

There is a button to invert the member checking of a collection. This is typically useful when you want to split a decadal file into two different collections.

Creating .rwl file headers

There is a menu command for you to copy a .rwl file header from one collection to another.

.rwl file precision

.rwl files can be written in 0.001 units, not only in 0.01 units!
This is selected through the menu command Settings/More settings.

CooRecorder:

Font size and color can be set for point numbers and labels.
Bolded numbers are easier to see!
Peculiar growth of that Norway spruce above!!! :-)

Font and color information can even be written into the .pos file and used when the file is later opened.
This is useful when a coordinate file is used to set points and text on a map or on some other picture.

There is an Erase command to erase all points between two other points!
It can be accessed from the menu (More/Erase all points...) or by the E-key on your keyboard.

There is a setting which will make the Comments box pop up automatically when you open an image to create a new coordinate file.
