= Summary Files Specification for RAREMETAL =
RAREMETAL use summary statistics files to perform meta-analysis. These includes (1) score statistics file and (2) covariance file.
Both [[RAREMETALWORKER|RAREMETALWORKER]] and [http://genome.sph.umich.edu/wiki/Rvtests '''rvtests'''] can generate these summary statistics files.
== Input score test statistics file ==
* === Format===
Header lines begins with '#' or 'CHROM'. After header part, we listed the meaning of each column as following:
# PVALUE P-value
* === RAREMETALWORKER === RAREMETALWORKER generates prefix.traitName.singlevar.score.txt, e.g. prefix.HDL.singlevar.score.txt

Covariance test statistics contains the LD matrix among a variant and the adjacent markers within a prefixed-sized window. The default window size is 1MB. It has the following format:
* === Format ===
# CHROM Chromosome
# COV (rvtests only) Covariance matrix between test statistics
* === RAREMETALWORKER ===RAREMETALWORKER generates prefix.traitName.singlevar.cov.txt, e.g. prefix.HDL.singlevar.cov.txt
