a vector of analytes (genes or metabolites) that need to be searched


number of genes analyzed in the experiment (e.g. background) (default is 20000, with assumption that analyte_type is "genes")


whether input is "names" or "ids" (default is "ids", must be the same for analytes and background)


"metabolites" or "genes" (default is "metabolites")


T/F if true, all pathways are used for multiple comparison corrections; if false, only pathways covering user analytes will be used (default is "F")


alternative hypothesis test passed on to fisher.test(). Options are two.sided, greater, or less (default is "less")


the minimum number of pathway members (genes and metabolites) to include the pathway in the output (default = 5)


the maximum number of pathway memnbers (genes and metaboltes) to include the pathway in the output (default = 150)


type of background that is input by the user. Opions are "database" if user wants all analytes from the RaMP database will be used; "file", if user wants to input a file with a list of background analytes; "list", if user wants to input a vector of analyte IDs; "biospecimen", if user wants to specify a biospecimen type (e.g. blood, adipose tissue, etc.) and have those biospecimen-specific analytes used. For genes, only the "database" option is used.


background to be used for Fisher's tests. If parameter 'background_type="database"', this parameter is ignored (default="database"); if parameter 'background_type= "file"', then 'background' should be a file name (with directory); if 'background_type="list"', then 'background' should be a vector of RaMP IDs; if 'backgroud_type="biospecimen"' then users should specify one of the following: "Blood", "Adipose tissue", "Heart", "Urine", "Brain", "Liver", "Kidney", "Saliva", and "Feces"


If "RaMP" (default), use pathway definitions within RaMP-DB. Else, supply path to gmx file containing custom pathway definitions. GMX files are a tab-separated format that contain one analyte set per column, with the name of the set in the first row, and constituent analytes in subsequent rows


a dataframe with columns containing pathway ID, fisher's p value, user analytes in pathway, and total analytes in pathway
