MetaCache v0.8.0

New feature "Coverage Filter"

Option -cov-percentile <p> removes the p-th percentile of hit targets (reference genomes) with the lowest coverage. A first pass does the normal mapping of queries (reads) to targets (reference genomes). The actual classification is then done in a second pass using only the remaining hit targets.

This will lead to a very small increase in runtime and memory consumption but can improve accuracy by detecting and removing stray false positive hits.

The coverage filter is deactivated by default.

Other Changes

• improved multi-threading in query mode
