**What it does**

`Pangolin <https://cov-lineages.org/pangolin.html>`_
(Phylogenetic Assignment of Named Global Outbreak LINeages) is used to assign a
SARS-CoV-2 genome sequence the most likely lineage based on the PANGO
nomenclature system.

**Data sources/versioning and reproducibility**

Pangolin uses the
`pangolin-data <https://github.com/cov-lineages/pangolin-data>`_ repository as
a source of its required model, protobuf, designation hash and alias files, and
the `constellations <https://github.com/cov-lineages/constellations>`_
repository for `scorpio <https://github.com/cov-lineages/scorpio>`_ -based
assignment of lineages of concern.

The tool ships with copies of these two data packages, and using these shipped
versions is *recommended* for reproducibility (even across Galaxy servers) and
speed of job execution.

If your instance of Galaxy offers cached alternative versions of
`pangolin-data` and/or `constellations`, you will be able to use them instead
of the shipped versions, which can be useful to reproduce results obtained
earlier with previous versions of pangolin.

Finally, you have the option to *download the latest version* of each data
package at job runtime.

.. class:: warningmark

   You can use this option as a workaround to get the most up-to-date lineage
   assignments even before the next Galaxy tool update (or before an admin
   installs new cached data versions on your server), but be aware of the
   following limitations:

1. Using latest downloaded data package versions renders results hard to
   reproduce (e.g. rerunning a corresponding job will cause also a fresh
   data download, which may yield different data versions as in the intial
   run).

2. Downloaded latest versions of the data packages may be incompatible
   with the *pangolin* and *scorpio* version run by the tool, which can
   result in failing tool runs, but occasionally also in harder to diagnose
   lineage assignment issues.

.. class:: infomark

   The exact combination of pangolin, inference engine (UShER/pangoLEARN),
   scorpio, and data packages that was used for a particular run of the tool
   can be extracted from the four "version" columns in the output (see below
   for details).

   In addition, lineage assignment with pangolin can be affected by the exact
   versions of additional underlying software. The packaged versions of all
   relevant dependencies are listed in the *Requirements* section below. This
   section is the equivalent to running `pangolin --all-versions` on the
   command line except that the listed versions of *pangolin-data* and
   *constellations* are the ones installed with pangolin and may have been
   overridden with the versions reported in the corresponding output columns
   at tool runtime.

**Output**

The main output of the tool is a tabular file with one line per input sequence
and with columns providing the
`following information <https://cov-lineages.org/resources/pangolin/output.html>`_:

taxon:
    The name of the input sequence

lineage:
    The most likely lineage assigned to a given sequence based on the inference
    engine used and the SARS-CoV-2 diversity designated.
    This assignment is sensitive to missing data at key sites.

conflict:
    If a sequence can fit into more than one category, the conflict score will
    be greater than 0 and reflect the number of categories the sequence could
    fit into.
    If the conflict score is 0, this means that within the current assignment
    model / lineage tree there is only one category that the sequence could
    plausibly be assigned to.

ambiguity_score:
    This score is a function of the quantity of missing data in a sequence.
    It represents the proportion of relevant sites in a sequence which were
    imputed to the reference values.
    A score of 1 indicates that no sites were imputed, while a score of 0
    indicates that more sites were imputed than were not imputed.
    This score only includes sites which are used by the assignment engine to
    classify a sequence.

scorpio_call:
    If a query is assigned a constellation by scorpio this call is output in
    this column.
    The full set of constellations searched by default can be found at the
    constellations repository.

scorpio_support:
    The support score is the proportion of defining variants which have the
    alternative allele in the sequence.

scorpio_conflict:
    The conflict score is the proportion of defining variants which have the
    reference allele in the sequence. Ambiguous/other non-ref/alt bases at each
    of the variant positions contribute only to the denominators of these
    scores.

scorpio_notes:
    A notes column specific to the scorpio output.

version:
    A version number that represents both the inference method and the
    pangolin-data version number, which as of pangolin 4.0 corresponds to the
    pango-designation version used to prepare the inference files. For example:

    PANGO-1.2 indicates an identical sequence has been previously designated
    this lineage, and has so gone through manual curation.
    The number 1.2 indicates the version of pango-designation that this
    assignment is based on. These hashes and pango-designation version are
    bundled with the pangoLEARN and UShER models.

    PLEARN-1.2 indicates that this sequence is different from any previously
    designated and that the pangoLEARN model was used as an inference engine to
    predict the most likely lineage based on the given version of
    pango-designation upon which the pangoLEARN model was trained.

    PUSHER-1.2 indicates that this sequence is different from any previously
    designated and that UShER was used as an inference engine with fast tree
    placement and parsimony-based lineage assignment, based on a guide tree
    (protobuf) file built from the data in a given pango-designation release
    version.

pangolin_version:
    The version of pangolin software running.

scorpio_version:
    The version of the scorpio software installed.

constellation_version:
    The version of constellations that scorpio has used to curate the lineage
    assignment.

is_designated:
    A boolean (True/False) column indicating whether that particular sequence
    has been offically designated a lineage (via pango-designation).

qc_status:
    Indicates whether the sequence passed the QC thresholds for minimum length
    and maximum N content.

qc_notes:
    Notes specific to the QC checks run on the sequences.

note:
    If any conflicts arose during assignment, this field will output the
    alternative assignments. If the sequence failed QC this field will describe
    why.
    If the sequence met the SNP thresholds for scorpio to call a constellation,
    it’ll describe the exact SNP counts of Alt, Ref and Amb (alternative,
    reference and ambiguous) alleles for that call.
