`bfile`	Vector of base file names of the binary file set used for the analysis. See details for construction and instructions.
`assoc`	Vector of file names and paths to the assoc files with the beta and P values used to construct the score.
`p`	A vector of P value thresholds to test each score at.
`pheno`	Vector or file path to phenotype to use for association analysis. This defaults to using the phenotype in the .fam file provided, though you can optionally provide a PLINK style phenotype file.
`mode`	See details. If mode is set to 1, then P value thresholds are estimated seperately for each of the different scores prior to their combination. If mode is set to 2, then P values thresholds are estimated all together to create the optimal score. Mode 2 is significantly slower than mode 1 for obvious reasons.
`training`	The algorithm used to train the scores. Defaults to 10 times cross validation.
