Instead of transforming the data and directly passing it into PyGWAS, make sure to pass the un-transformed phenotype values and let PyGWAS transform it.
Additionally make sure to pass all phenotype values and not only the ones from the Study so that the transformation is applied to all of them instead of only the overlap. PyGWAS will make sure to calculate the overlap and filter missing genotypes
