GET-Evidence

Background:

The "latest-flat.tsv" link on the Downloads page (http://evidence.personalgenomes.org/download/latest/flat/latest-flat.tsv) comes straight from a database table. That table contains a summary view of each variant, and each variant's row is updated when something attached to that variant changes. When the summary format changes (e.g. new column) the whole table has to be refreshed, which takes a couple of hours.

Therefore, this ticket probably indicates a bug in the download code (public_html/download.php) or the "refresh entire summary table" program (update_flat_summary.php) causing some variants to be skipped -- or a bug that causes the "primary variant entry" to be missing from the "latest" snapshot (like this bug).

(Missing "update summary when something changes" code could also cause "download out of date" problems.)

There is also a cached version of latest-flat available here:

• http://evidence.personalgenomes.org/latest-flat.tsv
• http://evidence.personalgenomes.org/latest-flat.tsv.gz

These files are updated nightly, and the web server includes the update time in the HTTP response headers, so if you choose to use these links -- and assuming your browser/client pays attention to the HTTP headers and sets the file modification time accordingly, like wget does -- the mod time on your saved file should be the time when the cached copy was updated.
