Path to comma-separated file containing information about the Xenium experiment. (eg; meta,path-to-xenium-bundle,path-to-morphology.ome.tif))

The output directory where the results will be saved. You have to use absolute paths to storage on Cloud infrastructure.

Mode in which the pipeline is to be run. Either image-based segmentation, coordinate-based segmentation, segmentation-free analysis or data preview.

Segmentation method to run.

Path to gene panel JSON file to use for relabeling transcripts with the correct gene.

Path to qupath segmentation file in GeoJSON format.

Image alignment file containing similarity transform matrix. (e.g., the _imagealignment.csv file exported from Xenium Explorer)

Model to use for running or starting training.

Prior segmentation mask from other segmentation methods.

Fasta file for the probe sequences used in the xenium experiment.

Path to the directory containing genomic features (.gff) and fasta (.fa) files used as reference annotations.

Gene synonyms that may have been counted as off-targets but simply differ in name.

Email address for completion summary.

MultiQC report title. Printed as page header, used for filename if not otherwise specified.

Whether to run the qc layer in the pipeline.

Whether to run the off-target probe tracking.

Whether to run refinement on the image-based segmentation methods. Runs coordinate-based methods after the initial image-based segmentation run.

Whether to relabel genes with gene_panel.json file. True when gene_panel is provided.

Whether to run vanilla xeniumranger workflow.

Whether to only run nucleus segmentation.

Whether to only run nucleus segmentation.

Nuclei boundary expansion distance in µm. Default: 5 (Min: 0, Max: 15 if either boundary-stain or interior-stain are enabled and 100 if nucleus-expansion only)

Minimum intensity in photoelectrons (pe) to filter nuclei. Default: 100. (appropriate range of values is 0 to 99th percentile of image stack or 1000, whichever is larger)

Specify the name of the interior stain to use or disable. Supported for cell segmentation staining workflow output bundles. Possible options are: “18S” (default) or “disable”

Specify the name of the boundary stain to use or disable. Supported for cell segmentation staining workflow output bundles. Possible options are: “ATP1A1/CD45/E-Cadherin” (default) or “disable”

Whether to enhance the morphology.ome.tif file.

Device used for training. (e.g., cuda for GPU or cpu)

Method for KNN computation. (e.g., cuda for GPU-based computation)

Preset value for the proseg segmentation method.

List of image-based segmentation methods.

List of transcript-based segmentation methods.

List of segmentation-free methods.

Regex used to identify or match negative control samples in a dataset.

List of features to be passed to the ficture method. (eg: TP53,OCIAD1,BCAS3,SOX)

Whether to filter the transcripts.parquet file before running Baysor segmentation.

minimum Q-Score to pass filtering (default: 20.0)

only keep transcripts whose x-coordinate is greater than specified limit, if no limit is specified, the default minimum value will be 0.0

only keep transcripts whose x-coordinate is less than specified limit, if no limit is specified, the default value will retain all transcripts since Xenium slide is <24000 microns in x and y (default: 24000.0)

only keep transcripts whose y-coordinate is greater than specified limit, if no limit is specified, the default minimum value will be 0.0

only keep transcripts whose y-coordinate is less than specified limit, if no limit is specified, the default value will retain all transcripts since Xenium slide is <24000 microns in x and y (default: 24000.0)

number of slices along the x axis (default - 10)

number of slices along the y axis (default - 10)

Width of the tiles in pixels

Height of the tiles in pixels

Number of samples to process per training batch

Number of devices (GPUs) to use during training

Number of samples to process per batch during prediction

Whether to use connected components for grouping transcripts without direct nucleus association

Process only one sample at a time from a multi-sample samplesheet.

Number of sample(s) to process at a time from a multi-sample samplesheet. Works if buffered_samples is true.

Restrict parallelizing a process. Eg. restrict running cellpose cell and nuclei segmentation together if the resources are limited.
