Pipeline 4.1 supports local and remote execution in the same workflow. For example, you can have modules that run on LONI Pipeline server and also modules run on your local machine. You can connect them, the LONI Pipeline will run the workflow as if they were on the same machine. As always, you can shut down LONI Pipeline while your workflow is running. When you reconnect later, Pipeline will automatically resume your workflow by running the remaining local executions.
Pipeline now has a built-in visualization tool (LONI Viewer) that lets you view results as soon as the execution completes. Simply choose Insert -> New Viewer on the top menu or right click on the workflow canvas and select “New Viewer…”. You can give inputs to this viewer by connecting the input parameter of the viewer to the output of other modules. When the file is ready, a separate Viewer window will pop up with the file to display. You [...]

Pipeline version 4.1 is now available for download. New features include visualization tool, remote and local execution, find and replace in data modules, and so on. Click here for new feature highlights. There are also bug fixes, for a detailed list of the changes, please see the release notes.
The FSL modules in the pipeline library reference wrapper scripts for executables rather than making simple calls to the binaries. This is due mainly to the environmental variables that must be set for proper usage inside LONI’s cluster. The wrapper scripts were created using Microsoft’s Wordpad, which introduced a series of characters unrecognizable by our Linux nodes cause execution failures. This has been resolved by recreating such wrappers entirely on the server side. Please contact email@example.com if additional issues have arisen. [...]
Pipeline version 4.1 Alpha release is now available for internal LONI users. Please contact the Pipeline team if you are interested in testing the new version. See release notes for a list of new features and bug fixes. Public Beta release will be availble in the near future.
The problems that had plagued our cluster throughout the weekend and today have finally been resolved. The Pipeline server is running on our Linux cluster minus 30 compute nodes, which we will bring online as quickly as we can throughout the week.
