Liatir

Appearance

Install Liatir Beta ​

Liatir is a local-first desktop application. The application, its interface, your workspace index and your analysis history stay available without a network connection. Optional AI Models and external tools are installed only when you choose to use them.

Beta packages

Use only a package linked from the official Liatir website or GitHub organization. Platform packages will be published only after their signing and clean-machine release checks pass. An unsigned development build is not an official Beta package.

Platform status ​

PlatformScientific workflowsBeta installer status
macOS arm64Single-cell and native Nextflow paths verifiedLocal packaging verified; Developer ID signing and Apple notarization still required for public distribution
Windows 11 x86_64Single-cell Runtime Box support and Nextflow through WSL2 verifiedLocal NSIS installer verified, including a real silent install and uninstall; Authenticode code signing still required for public distribution

These rows describe tested paths, not every computer that may happen to run Liatir. See Beta support and troubleshooting before starting a long analysis.

macOS ​

An official macOS Beta is distributed as a signed and notarized .dmg:

  1. Download the macOS arm64 disk image from the official release page.
  2. Open the disk image and drag Liatir into Applications.
  3. Start Liatir from Applications and confirm that macOS identifies the expected Liatir developer.
  4. Create or select a workspace. Your scientific files are referenced in their existing locations; Liatir does not upload them.

Do not bypass a macOS warning for an unsigned or unidentified build. Report the package name and release version instead.

Application updates ​

Open Settings → Application updates and select Check for updates. Liatir does not contact the release feed automatically. When an update is available, Liatir downloads it, verifies its updater signature, and asks you to restart after installation.

An update is refused while a Job is running. Finish or cancel the Job first so an analysis is never interrupted by application replacement.

Migration and recovery ​

On first start after upgrading from an older build, Liatir copies legacy workspace and analysis indexes into its isolated application storage. The migration is one-time and non-destructive: original entries and user-visible Results are not deleted.

If the app does not reopen correctly after an update:

  1. preserve the Liatir application-data folder;
  2. reinstall the same official package or the previous supported package;
  3. reopen Liatir and inspect Jobs and Results;
  4. export diagnostics before removing any application data.

Windows ​

An official Windows Beta is distributed as a code-signed .exe installer built with NSIS:

  1. Download the Windows x86_64 installer from the official release page.
  2. Run it and confirm that Windows identifies the expected Liatir publisher.
  3. Liatir installs for the current user, so no administrator account is needed.
  4. Start Liatir from the Start menu and create or select a workspace.

Windows SmartScreen warns about an installer it does not recognise. Do not choose Run anyway for a Beta package: report the filename and version instead.

To run Nextflow workflows from Liatir on Windows, install Nextflow and a compatible Java inside an x86_64 WSL2 distribution. Liatir drives that distribution; there is no native Windows Nextflow.

Linux ​

An official Linux Beta is distributed as a .deb, an .rpm or an AppImage for x86_64:

  1. Download the package that matches your distribution.
  2. Install it with your package manager, or make the AppImage executable and run it directly.
  3. Start Liatir and create or select a workspace.

Liatir needs a WebKitGTK-based webview, which the .deb and .rpm packages declare as a dependency.

Uninstall on macOS ​

Quit Liatir, then move Liatir.app from Applications to the Trash. Removing the app does not remove your source datasets, Results, installed AI Models, or workspace metadata. This retention is intentional so reinstalling does not destroy scientific work.

If you also want to remove all Liatir-managed state, first back up any Results you need, then remove ~/Library/Application Support/app.liatir.app. Files you kept elsewhere on disk are not owned or deleted by Liatir.

Uninstall on Windows ​

Close Liatir, then remove Liatir from Settings → Apps → Installed apps, or run the uninstall.exe that sits in the installation directory. This removes the application, its Start menu entry and its uninstall registration.

It does not remove your source datasets, Results, installed AI Models or workspace metadata. To remove all Liatir-managed state as well, back up any Results you need first, then remove %APPDATA%pp.liatir.app. Managed Python environments for Plugins are rebuildable and live separately under %LOCALAPPDATA%pp.liatir.app; removing them only means Liatir recreates them the next time a Plugin runs.

Uninstall on Linux ​

Remove the package with your package manager, or delete the AppImage file. Liatir-managed state stays in $XDG_DATA_HOME/app.liatir.app, which defaults to ~/.local/share/app.liatir.app; remove it only after backing up any Results you need.
