)

`metadata_id`	Synapse ID to clean metadata file with sample identifiers in a column and variables of interest as column names. There cannot be any missing values.
`metadata_version`	Optionally, include Synapse file version number. If omitted, current version will be downloaded.
`counts_id`	Synapse ID to counts data frame with identifiers to the metadata as column names and gene ids in a column.
`counts_version`	Optionally, include Synapse file version number.
`gene_id_input`	Column name of the gene ids in the counts_id file.
`factor_input`	Vector of factor variables. Variables must be present in the metadata as column names.
`continuous_input`	Vector of continuous variables. Variables must be present in the metadata as column names.
`gene_id`	Column name of gene Ids
`biomart_id`	Synapse ID to biomart object.
`biomart_version`	Optionally, include Synapse file version number.
`host`	An optional character vector specifying the release version. This specification is highly recommended for a reproducible workflow. (see `"biomaRt::listEnsemblArchives()"`)
`filters`	A character vector listing biomaRt query filters. (For a list of filters see `"biomaRt::listFilters()"`)
`organism`	A character vector of the organism name. This argument takes partial strings. For example,"hsa" will match "hsapiens_gene_ensembl".
`conditions`	Conditions to bin gene counts that correspond to variables in 'md'.
