Tools I have written

I have written several tools for genetic genealogy to make pictures of DNA segment data on a chromosome style chart. Pictures are a very useful way to sift through your segment overlap data.

  • Ancestor Chromosome Mapper: Make a map of which ancestor contributed which segment to you. Can show up to 10 ancestors on each side. Display is on two tracks, one for maternal and the other for paternal ancestors.
  • Overlapping Segment Mapper: Look at overlapping DNA segments  from up to 40 people in a chromosome chart. Display is stacked on four tracks to allow for display of overlaps.
  • One Chromosome Mapper: Sometimes you would like to see the detailed picture of overlapping DNA segments on one chromosome. This tool shows you up to 40 of those.

Another tool I have written is:
