genomicper (version 1.8)

read_pvals: Read GWAS p-values of association and Merge with SNP annotations

Description

Read GWAS p-values of association and Merge with SNP annotations for analysis

Usage

read_pvals(data_name="",snps_ann="",from="workspace")

Value

Dataframe: name; chromosome; Location; GeneID; Symbol; Orientation; Trait1; TraitN

Arguments

data_name

GWAS p_values (tab delimited file)(SNP_IDs Trait1 Trait2 ...TraitN)

snps_ann

SNPs Annotation (SNPsAnnotation). Genomicper uses entrez gene ids to annotate
associate SNPs-to genes-pathways.
The annotation MUST match your data input (coordinates and chromosome format)
Any SNP ID is valid, as long the ID is set as character
The examples below show an option on how to annotate the SNPs prior the use of genomicper

from

Datasets location. Values "workspace" OR "directory"
