Discussion Overview

The discussion centers around the analysis and visualization of raw genetic data obtained from a dog's genome, specifically focusing on data in a .TPED file format and the use of PLINK software. Participants explore various methods for visualizing this genetic information, including potential artistic representations and comparisons to existing genetic maps.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant mentions having raw genetic data consisting of 200,000 base pairs across 41 chromosomes and seeks options for visualization.
  • Another participant suggests creating a karyotype as a visualization method, proposing the use of code to aggregate the data into linear representations of chromosomes with centromeres.
  • A different participant expresses uncertainty about their coding skills but acknowledges the karyotype suggestion.
  • Another contribution points out the potential availability of existing genetic maps and chromosomal images of dog genomes, suggesting that comparing the participant's dog's genome to a "normal" genome could yield interesting insights.
  • This participant also proposes investigating predicted features based on identified alleles and their correlation with the dog's behaviors, referencing a related article on dog breeds and behavior.

Areas of Agreement / Disagreement

Participants express various ideas for visualizing genetic data, but there is no consensus on a specific method or approach. Multiple suggestions and perspectives remain open for exploration.

Contextual Notes

The discussion includes assumptions about the format and content of the genetic data, as well as the feasibility of coding for visualization, which remains unresolved.

Well I just checked out my boy's breed of dog. Not what we expected...But the analysis came with some raw data, 200,000 base pairs on ... 41 chromosomes. They're in a .TPED file, which can be opened in Excel. Apparently, it an also be analyzed using PLINK software.

Wondering what I can do to visualize this data in a poster or something.

I mean, I could do it myself manually, but are there any existing options?

Have you considered making making a karyotype?

This will make far more sense to most people, kind of intuitive.
This is what karyorypes look like:

Assuming your data is presented as chromosome groups - DNA from one chromosome, then the next.

Write come code to aggregate the data into 41 linear blobs. Add a "centromere as a wider dummy blob" somewhere in the middle of each "chromosome".

Sort of free form art based on real data.

Sure.

I think my coding days are behind me.
 
There are probably already genetic maps and chromosomal pictures of dog genome available some where.
It might be interesting to know what are the major differences in your dog's genome vs. "normal", and then mapping them to the already known dog genome.
If lots of them map to a single location, maybe its something like a deletion (exciting!).

A list of predicted features your dog might have, based on its molecularly identified alleles that differ from "normal", would be interesting to compare with the dog's actual behaviors.
A big article on how much a dog or its breed influences its behavior and how that compares to the dog's genetic make-up: (https://www.physicsforums.com/threads/big-article-on-dog-breeds-in-science.1014733/).
They have looked at lots of behaviors and compared them with breed and genomic sequence.
That would probably be a good step on the way to a better genetic understanding of your dog.
