From ProMeta 3 to ProMeta 4

ProMeta 3 was a Java desktop application. ProMeta 4 is its successor: the statistical engine was rebuilt, and it now runs in the browser, with no Java, no installation and no operating-system compatibility issues. It is free and open source.

Importing your .prm files

• In the app: the Workspace has an import tool for legacy .prm files. It converts them to a modern .prometa project and replaces the current project after you confirm. A separate converter also gives you the source CSV.
• On the command line: prometa import-pm3 extracts a source CSV and a modern project from a .prm file (see the commands).

Recodes, dataset definitions and analysis definitions are carried over where they can be represented. Check the imported project before relying on it.

What changed

• Runs in the browser; data stays on your device (see Data & Security).
• More models (multilevel, cluster-robust) and more analyses (see publication bias).
• Plot editors for forest, funnel, scatter and radial plots.
• A command-line tool for scripting.

ProMeta 4 is in public beta; see the known bugs.
