This program preprocesses the SNPRef tables in SAPP and populates the SNPTree tables with the internal structure of the current haplotree. This saves processing time when running the SNPTree tool.
NOTE: SAPP uses its internal Y-SNP tree to distinguish incompatible SNPs when SNP results are entered. This tree is intended to represent the major consistent public SNPs discovered by citizen-scientists and may not be identical to other Y-SNPs trees such as the ones published by Family Tree DNA, YFull, or other sites.
Inputs and Outputs are described in more detail at the links above.
