First run (marked in blue) of fixed differences corresponds to the Idd26 locus.In the above table the runs of fixed differences and what they are is listed below: When the VCF file from a published study is run through the script will generate a graph like below:

Ggplot(data.m, aes(Names, value,fill = variable)) + geom_bar(stat='identity',position='dodge')+ xlab('Allele frequency bins') + ylab('Number of sites') The rscript makebars is used to read in each of the site frequency spectrum's at the different genotype quality thresholds and generate a barplot of the SFS.

The below shell script takes vcf file as an argument in the for loop and calculates the allele frequencies using VCFTools.

Example code from the web was updated to use a bed file as input and print the GERP score for each base within the bed intervals. Here, we obtain the GERP scores for each base of all these exons. GERP scores could not obtained for 8 of these genes. A total of 4018 exons could be found for these 135 genes.
