Read 'NanoStringGeoMxSet'

Description

Create an instance of class NanoStringGeoMxSet by reading data from NanoString GeoMx Digital Count Conversion (DCC) data.

Usage

readNanoStringGeoMxSet(dccFiles, pkcFiles, phenoDataFile, 
                       phenoDataSheet, phenoDataDccColName = "Sample_ID",
                       phenoDataColPrefix = "", protocolDataColNames = NULL,
                       experimentDataColNames = NULL,  
                       configFile = NULL, analyte = "RNA",
                       defaultPKCVersions = NULL, ...)

Arguments

dccFiles	A character vector containing the paths to the DCC files.
pkcFiles	A character vector representing the path to the corresponding PKC file.
phenoDataFile	Character string representing the path to the corresponding phenotypic excel data file. It is recommended to use the Lab Worksheet in the exact order samples are provided in.
phenoDataSheet	Character string representing the excel sheet name containing the phenotypic data.
phenoDataDccColName	Character string identifying unique sample identifier column in phenoDataFile.
phenoDataColPrefix	An optional prefix to add to the phenoData column names to distinguish them from the names of assayData matrices, featureData columns, and protocolData columns.
protocolDataColNames	Character list of column names from phenoDataFile containing data about the experimental protocol or sequencing data.
experimentDataColNames	Character list of column names from phenoDataFile containing data about the experiment's meta-data.
configFile	An optional character string representing the path to the corresponding config file. This is used to ensure the only the correct PKC files are added
analyte	GeoMxSet objects can only hold one analyte at a time. For studies with multiple analytes, which one should be read in? Options: RNA (default) and Protein
defaultPKCVersions	Optional list of pkc file names to use as default if more than one pkc version of each module is provided.
...	Optional parameters to pass to readxl::read_xlsx function for annotation read in

Value

An instance of the NanoStringGeoMxSet class.
