makeMapp: makeMapp

In TimiRGeN: Time sensitive microRNA-mRNA integration, analysis and network generation tool

Description

Creates a dataframe which can be imported into pathvisio by use of the the MAPP plugin. This will add the filtered miRs to the wikipathway of interest on pathvisio. Follow instructions found in the vignette which show how to save this file and further instructions found in the issues section of the TimiRGeN gihub https://github.com/Krutik6/TimiRGeN/issues/2.

Usage

makeMapp(MAE, filt_df, miR_IDs_adj, dataType = '')

Arguments

MAE	MultiAssayExperiment to store the output of makeMapp. It is recommended to use the same MAE which stores the output from matrixFilter.
filt_df	Dataframe of mined miR-mRNA interactions. This is output of matrixFilter. It should be stored as an assay in the MAE used in the matrixFilter function.
miR_IDs_adj	Dataframes with adjusted gene IDs to account for -5p and -3p specific miRs. miR_adjusted_entrez or miR_adjusted_ensembl. Should be found as assays within the MAE used a getIdsMir function.
dataType	String which represents the gene ID used in this analysis. Either "En" (ensembl data) or "L" (entrez data).

Value

A dataframe containing microRNAs and adjusted gene IDs which can be saved as a text file to be imported into pathvisio via the MAPPapp. Output will be saved as an assay in the input MAE.

Examples

library(org.Mm.eg.db)

data(mm_miR)

data(mm_mRNA)

MAE <- startObject(miR = mm_miR, mRNA = mm_mRNA)

MAE <- getIdsMir(MAE, assay(MAE, 1), orgDB = org.Mm.eg.db, 'mmu')

MAE <- getIdsMrna(MAE, assay(MAE, 2), "useast", 'mmusculus')

Filt_df <- data.frame(row.names = c("mmu-miR-320-3p:Acss1",
                                     "mmu-miR-27a-3p:Odc1"),

MAE <- makeMapp(MAE, filt_df = Filt_df, miR_IDs_adj = assay(MAE, 5),
                dataType = 'L')
