RareMETAL Tutorial
Introduction
In this tutorial, we will show how to run RareMetalWorker and RareMETAL to perform meta analysis using example data sets.
RareMetalWorkr is the pre-processing tool to analyze data from individual studies and generate summary statistics for further meta analysis using RareMETAL.
RareMETAL is the tool to do gene-level meta analysis.
STEP 1: Install Software and Download Example Data Sets
- If RareMETAL and RareMetalWorker have not been installed on your local computer yet, please follow the following directions for installation. Install RareMetalWorker, Install RareMETAL
- Download the example data set for RareMetalWorker to your local drive: RareMetalWorker example data sets
- Go to your local path where the tar ball was saved then extract
tar xvzf raremetalworker.tutorial.tgz #extract cd rmw_tutorial
- Download the example data set for RareMetal to your local drive: RareMetalWorker example data sets
- Go to your local path where the tar ball was saved then extract
tar xvzf raremetal.tutorial.tgz #extract cd raremetal_tutorial
STEP 2: Run RareMetalWorker on Individual Studies
- The first example has 743 individuals coded as unrelated according to PED file (each person belongs to an individual family).
- there are ~1000 markers included in the VCF file.
- To analyze this sample accounting for hidden relatedness, an empirical kinship should be calculated.
- By using the following command, covariates are also adjusted and residuals inverse normalized on the fly.
