=== Specifying Weights in P-value Based Analysis ===
The weight for each MARKER can be stored in a column in the table (specified with the <code>WEIGHTLABEL</code> or <code>WEIGHT</code> commands).
The weight for each MARKER can be stored in a column in the table (specified with the <code>WEIGHTLABEL</code> or <code>WEIGHT</code> commands). Most commonly, the weight will be the number of individuals contributing to that particular p-value.
WEIGHTLABEL N
Alternatively, the same weight can be used for all markers for that inputfile (in which case the fixed weight can be set with the <code>DEFAULTWEIGHT</code> command). The WEIGHTLABEL command takes precedence over the DEFAULTWEIGHT command, so the WEIGHT column label in use must not match any columns in the inputfile.
