# UKBB-FinnGen meta-analysis file formats

The meta-analysis result files are TSV [tabix-indexed](http://www.htslib.org/doc/tabix.html) files compressed with bgzip, which contain the summary statistics from the FinnGen and UKBB analyses and the summary statistics of the meta-analysis. The columns of the table are described below.
