File:ParentalPolymorphismSNPSelector.zip

This script is designed to process VCF files by skipping the header lines and then examining each line to check the genotypes in the 10th and 11th columns, which correspond to the maternal and paternal lines in our specific dataset. It selects SNPs where both parental lines are homozygous but not identical, and where neither genotype is missing.

It's important to note that the script is tailored to the specific format of our VCF files, where the maternal and paternal genotypes are located in the 10th and 11th columns, respectively. The structure of VCF files can vary, and in cases where the maternal and paternal lines are located in different columns, the script would need to be modified accordingly. Therefore, while we will include this script as supplementary material in our manuscript, it may not be universally applicable without adjustments.
