DNA Gramplet

I apologize for jumping the gun on moving the DNA Gramplet documentation I did not realize the documentation was referring to an unreleased addon not available to anyone but yourself, which explains my confusion when I was attempting to update based on the existing version and seeing different results than your screenshots show :( Will you be sharing it for testing myself & possibly User:Matt are interested? --Gioto (talk) 22:21, 20 September 2020 (UTC)

Added access to test version at DNA. I will be pushing this once another PR has been accepted (Addon:SyncAssociationis loosely connected to the DNA gramplet) GaryGriffin (talk) 17:25, 20 Sep 2020 (PST)
Thanks, I'll try to check-it out in a few days. --Gioto (talk) 00:03, 26 September 2020 (UTC)

dna feedback from matt

GaryGriffin: Thank you for sharing. Testing seems to work fine. Some notes and ideas:

  1. The loading speed might become a problem. For 8 associations it already takes ~3 seconds to load.
  2. Overlapping segments are hidden below others and currently unaccessible. A way to draw overlapping segments in seperate rows might be an interesting feature in future.

Matt: Hmmm, I have 18 Associations for one person and it is less than a second to draw for me. I am on a 2013 Mac, so not the fastest system. This may be more of a function of PyCairo implementation on the platform. Can you provide more info on platform and range of overlaps.
  1. Are most of your segments tied to a maternal/paternal side or unknown (which can definitely get busy)? Almost all of mine are M/P known. The drawing format is the standard one (for each segment an M and a P section). I fear I would add more confusion if I diverted from that. See DNApainter as an example.
  2. I draw in order of Association. I cannot think of how I would draw in an order that guaranteed the largest was always behind all smaller overlaps. I have only 1 totally obscured overlap, so hadn't thought about this problem. I only realized I had this when I made the segments more transparent (see next item).
  3. Maybe if all were less opaque, it would be an easier view? Change line 330 of dna.py to the following. This will change the opacity to 0.5 for M/P and 0.33 for U. The one I posted was 1 for M/P and 0.5 for U. Would appreciate your feedback on this change.

GaryGriffin: I'm on Windows 10 using GrampsAIO64-5.1.3-1 and Pycairo 1.16.1. All segments are tied to a maternal/paternal side since I only added the known ones. I do have some segemnts overlapping since many of them are from the same common ancestor couple. Yes drawing one maternal and paternal row for each chromosome is standard, but the DNA Painter also has an option to expand and collapse these rows, so you can see all overlapping segments. (see: https://dnapainter.com/example, click on the chromosome number or the plus/minus icon)
