 **Summary**
 
 This tool will create a qq plot and a Manhattan plot for one or more GWA P value columns from a tabular
-dataset. For Manhatten plots, the data must include the chromosome (eg use 23,24,25 for x,y,mt...) and
+dataset. For Manhattan plots, the data must include the chromosome (eg use 23,24,25 for x,y,mt...) and
 offset. Many analysis files contain the required fields but even without chromosome and offset, a qq plot 
 can be created.
