Workflows

get promoter region + operate on genomic i... (1)

• Download

Finds the overlap between two datasets which contain genomic information (e.g. [gene id], chromosome name, gene start, gene end), plus some statistics. Returns rows of file_1 which overlap with the second file. A kolmogorov smirnov test is applied between the list that overlaps and the one that does not. NOTE: The library(GenomicRanges) is a prerequisite for this workflow

Map genes to chromosomal location (1)

• Download

This workflow maps a gene list to the genome using the biomart service, and afterwards computes a promoter region for each gene. The user needs to define the promoter region to be computed. The direction that a gene is transcribed is being taken into account in the "compute_promoter_region_with_strand" component. The variable "strand" is responsible for that. NOTE: The library(biomaRt) is a prerequisite for this workflow

****IMPORTANT****:if libraries: library(ArrayExpress), library(hgu133a.db), library(limma) are not installed in the local R installation, then they need to be installed before running this workflow. Original data come from Hodges et. al 2006 "Regional and cellular gene expression changes in human Huntington’s disease brain" This workflow loads the two necessary files (gene expression data & phenotype data), and creates the expression set object to be used by the R package limma, to test for ...

get promoter region + operate on genomic i... (5)

• Download

This workflow computes a promoter region for each gene that we provide as input carrying the genomic information. Then it computes the overlap between the two datasets that contain genomic information plus some statistics. Returns rows of file_1 which overlap with the second file. A kolmogorov smirnov test is applied between the list that overlaps and the one that does not. Uses the R package GenomicRanges.
