Global tree and separating out the WA-specific configs #30
Conversation
…pecific build configuration Subsequent commits will place the washington state specific configs and rules in this directory.
This separates the washginton-specific rules and configs from the new global workflow. Subsequent commits will tune global rules and configs, and rooting. The washginton-specific workflow can run via: nextstrain build phylogenetic --configfile build-configs/washington-state/config.yaml
Use AF260968 ('Egypt 1951') as the global reference and root, following Mencattelli et al, 2023 https://www.nature.com/articles/s41467-023-42185-7
…n phylogenetic analyses
Exclude several PAT strains that did not have the is_lab_host metadata field set to True. Exclude several strains that were either putative recombinants or were below the PAT FV537222 cluster.
Separate washington-state specific refine parameters from a more permissive global refine parameters.
Rooted global tree can be previewed here: https://next.nextstrain.org/staging/WNV/global/rooted |
Cool! Small note that something is fairly off in terms of molecular clock. You can see here https://nextstrain.org/staging/WNV/global/rooted?f_country=USA that the main USA clade has a common ancestor of ~1400 AD, while it should be ~1998. You can perhaps better see the correspondence here: https://nextstrain.org/staging/WNV/global/rooted:WNV/NA |
We're planning to fix the molecular clock or decide to split into lineage trees in a later PR (will write up a GitHub issue). Merging this to have a draft split of WA and global config files. |
Description of proposed changes
Separate out the WA-specific configs and some fine-tuning of the global tree.
