+```
+cellranger mkref -h
+```
+Prepare a reference for use with 10x analysis software. Requires a GTF and
+FASTA
+
+Usage: cellranger mkref [OPTIONS] --genome <GENOME_NAMES> --fasta <FASTA_FILES> --genes <GTF_FILES>
+
+Options:
+      --genome <GENOME_NAMES>
+          Unique genome name, used to name output folder [a-zA-Z0-9_-]+.
+          Specify multiple genomes by specifying this argument multiple
+          times; the output folder will be <name1>_and_<name2>
+      --fasta <FASTA_FILES>
+          Path to FASTA file containing your genome reference. Specify
+          multiple genomes by specifying this argument multiple times
+      --genes <GTF_FILES>
+          Path to genes GTF file containing annotated genes for your genome
+          reference. Specify multiple genomes by specifying this argument
+          multiple times
+      --nthreads <NUM_THREADS>
+          Number of threads used during STAR genome index generation.
+          Defaults to 1 [default: 1]
+      --memgb <MEM_GB>
+          Maximum memory (GB) used [default: 16]
+      --ref-version <REF_VERSION>
+          Optional reference version string to include with reference
+      --dry
+          Do not execute the pipeline. Generate a pipeline invocation (.mro)
+          file and stop
+      --jobmode <MODE>
+          Job manager to use. Valid options: local (default), sge, lsf,
+          slurm or path to a .template file. Search for help on "Cluster
+          Mode" at support.10xgenomics.com for more details on configuring
+          the pipeline to use a compute cluster
+      --localcores <NUM>
+          Set max cores the pipeline may request at one time. Only applies
+          to local jobs
+      --localmem <NUM>
+          Set max GB the pipeline may request at one time. Only applies to
+          local jobs
+      --localvmem <NUM>
+          Set max virtual address space in GB for the pipeline. Only applies
+          to local jobs
+      --mempercore <NUM>
+          Reserve enough threads for each job to ensure enough memory will
+          be available, assuming each core on your cluster has at least this
+          much memory available. Only applies to cluster jobmodes
+      --maxjobs <NUM>
+          Set max jobs submitted to cluster at one time. Only applies to
+          cluster jobmodes
+      --jobinterval <NUM>
+          Set delay between submitting jobs to cluster, in ms. Only applies
+          to cluster jobmodes
+      --overrides <PATH>
+          The path to a JSON file that specifies stage-level overrides for
+          cores and memory. Finer-grained than --localcores, --mempercore
+          and --localmem. Consult https://support.10xgenomics.com/ for an
+          example override file
+      --output-dir <PATH>
+          Output the results to this directory
+      --uiport <PORT>
+          Serve web UI at http://localhost:PORT
+      --disable-ui
+          Do not serve the web UI
+      --noexit
+          Keep web UI running after pipestance completes or fails
+      --nopreflight
