A GWAS file is a space- or tab-delimited result file from genome-wide association study (GWAS) analysis. These files include PLINK result files containing integrated map information (i.e., chromosomal location for each association).
File extensions for GWAS files are: .linear, .logistic, .assoc, .qassoc, .gwas
GWAS file must contain four columns (case-insensitive):
Columns can be in any order. Other columns besides the required ones are allowed. The file must be sorted by start position in ascending order. The p-value will be transformed to -log10 scale for plotting.
