<LinkableSection id={"v-1-7-1"} title={"v1.7.1 (January 23, 2024)"}>

- Fixed a bug to improve the method to import segmentation results generated from large image files (i.e., from IF or H&E images).
- Fixed a bug to enable importing segmentation results for smaller regions of the original image data.

</LinkableSection>

<LinkableSection id={"v-1-7"} title={"v1.7.0 (October 9, 2023)"}>

- Supports reanalysis of Xenium Onboard Analysis data up to latest version (see [version compatibility table](/support/software/xenium-ranger/1.7/getting-started/XR-getting-started-with-xenium-ranger#compatibility)).
- The image-based `import-segmentation --coordinate-transform` [option](/support/software/xenium-ranger/1.7/analysis/running-pipelines/XR-import-segmentation#xr-matrix) is now compatible with segmentation masks (previously limited to polygons).
- Improved memory usage in the `import-segmentation` pipeline (see updated [system requirements page](/support/software/xenium-ranger/1.7/release-notes/XR-system-requirements)).
- Fixed bug where input masks with discontinuous cells or nuclei caused Xenium Ranger to occasionally crash. An analysis summary alert was introduced to flag rare scenarios where discontinuities may lead to splitting of imported cells or nuclei.
- Several minor bug fixes in the analysis summary user interface.
- Improved preflight checks.
- Miscellaneous bug fixes.

</LinkableSection>

<LinkableSection id={"v-1-6"} title={"v1.6 (August 17, 2023)"}>

- Initial release.
- Resegment Xenium data with customizable nucleus expansion distance and the latest 10x cell segmentation algorithm.
- Import community-developed nucleus and cell segmentations in multiple popular formats (i.e., Baysor).
- Selected the wrong gene panel when you started the Xenium Analyzer run? Simply fix the mistake by using relabel.
- All pipelines produce the same output bundle as Xenium Onboard Analysis v1.6, so they are compatible with the same downstream visualization and analysis softwares (e.g., Xenium Explorer).
- Backwards compatible with all previous Xenium Onboard Analysis versions.

Release Notes for Xenium Ranger


<LinkableSection id={"overview"} title={"Hardware"}>

Xenium Ranger pipelines run on Linux systems that meet these minimum requirements:

- 8-core Intel or AMD processor (32 cores recommended) with `avx2`
- 64GB RAM (128GB recommended)
- 1TB free disk space
- 64-bit CentOS 7 and later/RedHat 7.4 or Ubuntu 16.04 and later; See the [10x Genomics OS Support](https://support.10xgenomics.com/os-support "10x Genomics Support") page for details.

Running `xeniumranger import-segmentation` with the following tissue area and input data have higher minimum memory requirements:

| Tissue area                                              | Input                                                 | Minimum memory |
| -------------------------------------------------------- | ----------------------------------------------------- | -------------- |
| 1cm<sup>2</sup> dataset (e.g., full coronal mouse brain) | Nucleus and cell label mask (e.g., from Cellpose)     | 64GB RAM       |
| Entire well                                              | Nucleus and cell label mask                           | 256GB RAM      |
| Entire well                                              | Nucleus and cell boundary (e.g., GeoJSON from QuPath) | 128GB RAM      |

The pipeline can also run on clusters that meet these additional minimum requirements:

- Shared filesystem (e.g. NFS)
- Slurm batch scheduling system

</LinkableSection>

<LinkableSection id={"resource-limits"} title={"Resource limits"}>

- Xenium Ranger runs with `--jobmode=local` by default, using 90% of available memory and all available cores. To restrict resource usage, please see the `--localcores` and `--localmem` arguments for `xeniumranger` subcommands.
- Many Linux systems have default user limits (ulimits) for maximum open files and maximum user processes as low as 1024 or 4096. Because Xenium Ranger spawns multiple processes per core, jobs that use a large number of cores can exceed these limits. 10x Genomics recommends higher limits.

| **Limit**        | **Recommendation**                        |
| ---------------- | ----------------------------------------- |
| user open files  | 16k                                       |
| system max files | 10k per GB RAM available to Xenium Ranger |
| user processes   | 64 per core available to Xenium Ranger    |

</LinkableSection>

<LinkableSection id={"computing-options"} title={"Computing options"}>

There are three primary ways to run Xenium Ranger:

1. **Single server**: Xenium Ranger can run directly on a dedicated server. This is the most straightforward approach and the easiest to troubleshoot. The majority of the information on this website uses the single server approach.
2. **[Job submission mode](/support/software/xenium-ranger/1.7/advanced/XR-job-submission-mode)**: Xenium Ranger can run using a _single_ node on the cluster. Less cluster coordination is required since all work is done on the same node. This method works well even with job schedulers that are not officially supported.
3. **[Cluster mode](/support/software/xenium-ranger/1.7/advanced/XR-cluster-mode)**: Xenium Ranger can run using _multiple_ nodes on the cluster. This method provides high performance, but is difficult to troubleshoot since cluster setup varies among institutions.

Recommendations and requirements, in order of computational speed (left to right):
| | Cluster Mode | Job Submission Mode | Single Server |
|---|---|---|----|
| **Recommended for** | Organizations using an HPC with SLURM for job scheduling | Organizations using an HPC | Users without access to an HPC |
| **Compute details** | Splits each analysis across multiple compute nodes to decrease run time | Runs each analysis on a single compute node | Runs each analysis directly on a dedicated server |
| **Requirements** | HPC with SLURM for job scheduling | HPC with most job schedulers |Linux computer with minimum 8 cores & 64 GB RAM (but see [above](#overview)) |
