To perform only a gene analysis, with no subsequent gene-set analysis, the --genes-only flag
can be added. This suppresses the creation of the .genes.raw file, and significantly reduces the running
time and memory required.
For studies where all we care about are getting the weight gene profiles for each GWAS, would be nice to provide this option to speed up analysis.
In the MAGMA manual (page 3) it mentions:
