Other Traits

Other traits can be thought of as qualitative or categorical traits. Examples include sex, brood, plot, etc. In some cases these factors will have been ``regressed out'', that is a regression of the quantitative trait of interest on the categorical trait will have been performed and the residuals used as the phenotypes in the analysis. Presently, they can be input via a file of filetype ``cross.inp'' but not automatically analyzed. One includes these other traits in the regression model by prepending a plus sign (+) to the other trait name. For example,

-Names of the other traits...
  1 +Sex
  2 -Line

would incorporate a Sex effect in the regression model, while ignoring the Line effect.
