== Key Features ==
== Brief Description ==
'''RAREMETAL''' is a computationally efficient tool for meta-analysis of rare variants using sequencing or genotyping array data. '''RAREMETAL''' takes summary statistics and LD matrices generated by [[Rare-Metal-Worker|'''RAREMETALWORKER''']], handles related and unrelated individuals, and supports both single variant and burden meta-analysis. '''RAREMETAL''' generated high quality plots by default and has options that allow users to build reports at different levels.
'''RAREMETAL''' is developed by Shuang Feng, Dajiang Liu and Gonçalo Abecasis. A R-package using the same methodology is [[RareMetals|available]]]. Manuscript for this tool is in preparation. Please contact sfengsph at umich dot edu for questions.
==== Prepare Input Files====
'''rareMETAL''' requires the following basic input files: summary statistics and covariance matrices of score statistics generated by '''rareMetalWorker''', a file with list of studies to be included and a group file if gene-level meta-analysis is expected.

==== QC Options ====
* '''rareMETAL''' allows filtering of variants from individual studies by their HWE pvalue and call rate, which are generated as part of the output from '''rareMetalWorker'''.
* To filter by HWE p-values, --hwe option should be used. The default is 0.0, which means not filtering any of the variants.
* To filter by call rate, --callRate option can be specified. The default is 0.0, which allows no filtering utilized.
