- Documentation is now available online for the augur CLI and Python API via Read The Docs: https://nextstrain-augur.readthedocs.io. The latest version on RTD points to the git master branch, and the stable version to the most recent tagged release. Instructions for building the docs locally are in the README.
- ancestral: New option to
--keep-ambiguous
, which will not infer nucleotides at ambiguous (N) sites on tip sequences and instead leave as 'N' See PR 280. - ancestral: New option to
--keep-overhangs
, which will not infer nucleotides for gaps on either side of the alignment and instead leave as '-'. See PR 286. - clades: This module has been reconfigured to identify clade defining mutations on
top of a reference rather than identifying mutations along the tree. The command
line arguments are the same except for the addition of
--reference
, which explicitly passes in a reference sequence. If--reference
is not defined, then reference will be drawn from the root node of the phylogeny by looking forsequence
attribute attached to root node of--tree
. See PR 288. - refine: Revise rooting behavior. Previously
--root
took 'best', 'residual', 'rsq' and 'min_dev' as options. In this update--root
takes 'best', least-squares', 'min_dev' and 'oldest' as rooting options. This eliminates 'residual' and 'rsq' as options. This is a backwards-incompatible change. This requires updating TreeTime to version 0.5.4 or above. See PR 263. - refine: Add
--keep-root
option that overrides--root
specification to preserve tree rooting. See PR 263. - refine: Add
--covariance
and--no-covariance
options that specify TreeTime behavior. See PR 263. - titers: This command now throws an
InsufficientDataException
if there are not sufficient titers to infer a model. This is paired with a new--allow-empty-model
flag that proceeds past theInsufficientDataException
and writes out a model JSON corresponding to an 'empty' model. See PR 281. - By default JSONs are written with
index=1
to give a pretty-printed JSON. However, this adds significant file size to large tree JSONs. If the environment variableAUGUR_MINIFY_JSON
is set then minified JSONs are printed instead. This mirror the explicit--minify-json
argument available toaugur export
. See PR 278.
- export: Cast numeric values to strings for export. See issue 287.
- export: Legend order preserves ordering passed in by user for traits that have default colorings ('country' and 'region'). See PR 284.
- refine: Previously, the
--root
argument was silently ignored when no timetree was inferred. Re-rooting with an outgroup is sensible even without a timetree. See PR 282.
-
distance: New interface for specifying distances between sequences. This is a backwards-incompatible change. Refer to
augur distance --help
for all the details. -
export: Add a
--minify-json
flag to omit indentation in Auspice JSONs.
- frequencies: Emit one-based coordinates (instead of zero-based) for KDE-based mutation frequencies
- Include additional country lat/longs in base data
- titers: fix calculation of
mean_potentency
for model export
- Update to TreeTime 0.5.3
- tree: Fix bug in printing causing errors in Python versions <3.6
- tree: Alter site masking to not be so memory intensive
- filter: Allow negative matches to
--exclude-where
. For example,--exclude-where country!=usa
would exclude all samples where metadatacountry
does not equalusa
. - tree: Allow
--exclude-sites
to work with FASTA input. Ensure that indexing of input sites is one-based.
- fix loading of strains when loading titers from file, previously strains had not been filtered to match the tree appropriately
- frequencies: Add
--ignore-char
and--minimal-clade-size
as options. - frequencies: Include
--stiffness
and--inertia
as options. - titers: Allow multiple titer date files in
--titers
import.
- filter: Fix
--non-nucleotide
call to include?
as allowed character. - tree: Fix
--method raxml
to properly delimit interim RAxML output so that simultaneous builds don't conflict.
- Include additional country lat/longs in base data
- frequencies: Include
counts
inaugur frequencies
output JSON to support downstream plotting.
- Include additional country lat/longs in base data
- filter: Add
--non-nucleotide
option to remove sequences with non-conforming nucleotide characters.
- Revise treatment of
-
,augur parse
to leave-
as is and remove white space. Also delimit[
and]
to_
. - Fix bug in naming of temp IQTREE fixes to prevent conflicts from simultaneous builds.
- Include additional country lat/longs in base data
- Remove non-modular measles build in favor of nextstrain/measles repo.
- Update dependencies
- filter: Fix
--include-where
. Adds anall_seq
variable needed by the logic to include records by value. This was previously working for VCF but threw an exception for sequences in FASTA format. - Update flu reference viruses and lat longs.
- Update dependencies
- reconstruct-sequences: Include
augur reconstruct-sequences
module that reconstructs alignments from mutations inferred on the tree - distance: Include
augur distance
module that calculates the distance between amino acid sequences across entire genes or at a predefined subset of sites - lbi: Include
augur lbi
module that calculates local branching index (LBI) for a given tree and one or more sets of parameters. - frequencies: Include
--method kde
as option toaugur frequencies
, separate from the existing--method diffusion
logic. KDE frequencies are faster and better for smaller clades but don't extrapolate as well as diffusion frequencies. - titers: Enable annotation of nodes in a tree from the substitution model
- translate: Nucleotide ("nuc") annotation for non-bacterial builds starts at 0 again, not 1, fixing a regression.
- Schemas: Correct coordinate system description for genome start/end annotations.
- validate: Fix regression for gene names containing an asterisk.
- Fix Travis CI tests which were silently not running.
-
refine: Add a
--clock-std-dev
option -
traits: Add a
--sampling-bias-correction
option for mugration model -
validate: Gene names in tree annotations may now contain hyphens. Compatible with Auspice version 1.33.0 and later.
-
All JSON is now emitted with sorted keys, making it easier to diff and run other textual comparisons against output.
-
filter: Only consider A, T, C, and G when calculating sequence length for the
--min-length
option. -
filter: Allow comments in files passed to
--exclude
. -
filter: Ignore case when matching trait values against excluded values.
-
Normalize custom geographic names to lower case for consistent matching.
-
Fix typo in geographic entry for
netherlands
. -
Schemas: Reconcile naming patterns used in gene definitions and tree annotations.
-
Upgrade TreeTime dependency to 0.5.x and at least 0.5.1.
-
Add an
environment.yml
file for use withconda env create
. -
Stop testing under Python 2.7 on Travis CI.
- translate: Fix broken
--help
message
-
align and tree: The --nthreads option now accepts the special value "auto" to automatically set the number of threads to the number of CPU cores available.
-
Alias
augur --version
toaugur version
-
tree: The --nthreads option is now respected. Previously all tree builders were ignoring the value and using either 2 threads (RAxML, IQ-TREE) or as many threads as cores (FastTree, if the OpenMP version).
-
translate: Check for and, if necessary pad, nucleotide sequences which aren't a multiple of 3 earlier to avoid errors later.
-
export: Optionally write inferred nucleotide and amino acid sequences (or mutations) to a separate file.
-
export: Omit genes with no amino acid mutations.
-
validate: Allow underscores in gene names.
-
refine: Remove unused --nthreads argument.
-
ancestral, filter, tree, refine: Exit 1 instead of -1 on error.
-
Print the help message, instead of throwing an exception, when
augur
is run without arguments.
-
Briefly describe each command in its
--help
output and in the globalaugur --help
output. -
Revamp README to emphasize new, modular augur and make it suitable for inclusion on PyPi.

-
Include URLs for bug reports, the change log, and the source on PyPi.

Ignore distribution egg-info build files
-
Export: Add safety checks for optional annotations and geo data
-

augur version
command reports the running version.
