available_cpu_cores
(fallback: int = 1) → int¶ Returns the number (an int) of CPU cores available to this process, if determinable, otherwise the number of CPU cores available to the computer, if determinable, otherwise the fallback number (which defaults to 1).

(json_dict, root=True)¶ Returns a Bio.Phylo tree corresponding to the given JSON dictionary exported by tree_to_json.
Assigns links back to parent nodes for the root of the tree.
>>> import json >>> json_fh = open("tests/data/json_tree_to_nexus/flu_h3n2_ha_3y_tree.json", "r") >>> json_dict = json.load(json_fh) >>> tree = json_to_tree(json_dict) >>> tree.name 'NODE_0002020' >>> len(tree.clades) 2 >>> tree.clades[0].name 'NODE_0001489' >>> hasattr(tree, "attr") True >>> "dTiter" in tree.attr True >>> tree.clades[0].parent.name 'NODE_0002020'

load_features
(reference, feature_names=None)¶
-

myopen
(fname, mode)¶
-

nthreads_value
(value)¶ Argument value validation and casting function for –nthreads.
-

read_colors
(overrides=None, use_defaults=True)¶

read_node_data
(fnames, tree=None)¶ parse the “nodes” field of the given JSONs and join the data together
-
augur.utils.
run_shell_command
(cmd, raise_errors=False, extra_env=None)¶ Run the given command string via the shell with error checking.
Returns True if the command exits normally. Returns False if the command exits with failure and “raise_errors” is False (the default). When “raise_errors” is True, exceptions are rethrown.
If an extra_env mapping is passed, the provided keys and values are overlayed onto the default subprocess environment.
-
augur.utils.
write_VCF_translation
(prot_dict, vcf_file_name, ref_file_name)¶ Writes out a VCF-style file (which seems to be minimally handleable by vcftools and pyvcf) of the AA differences between sequences and the reference. This is a similar format created/used by read_in_vcf except that there is one of these dicts (with sequences, reference, positions) for EACH gene.
Also writes out a fasta of the reference alignment.

write_json
(data, file_name, indent=1)¶ Write data as JSON to the given file_name, creating parent directories if necessary.

is defined with a truthy value, the default indent is insteadNone
.
