Week 11
Introduction
We are going to practice making Manhattan plots today.
Investigate your data.
What are your columns?
How many markers are there?
How are the markers distributed across the chromosomes?
Make a Manhattan plot.
Color by chromosome, make sure the x-axis breaks are appropriate, be sure your y-axis is -log10 pvalue. Label the top 3 most significant points with their SNP number.
