==== Centromere Areas ====
Machines have difficulties to read the area around the centromere. There are less SNPs to read, therefore there is higher probability of false positive matches. For example, if you have a match exactly around the centromere, then it is most probably a false positive match. The area of the centromere id dependent on the Build (36, 37, or 38). For example, the list for Build 37 (the most common) is
<pre>
show-centromere=1
</pre>
==== Untested Areas ====
There are areas in the DNA test that are generally not tested as they are not reliable indicators of a match. If you want to visualize these areas, create a dummy person and add an association with the following DNA segments.
