Placeholder for documentation for 'smasher', the taxonomy combiner. See file NEWS.md for release notes.
Taxonomies are represented as directories, see https://github.com/OpenTreeOfLife/opentree/wiki/Interim-taxonomy-file-format
To test to see whether you can run Smasher, do 'make aster'.
To create a new version of OTT:
-
Put previous version in tax/prev_ott/ . The taxonomy file name should be taxonomy.tsv, similarly synonyms.tsv and so on. (Around version 2.2 the file names changed from no extension to a .tsv extension.)
-
Edit definition of WHICH in Makefile to be new version number, e.g. WHICH=2.7.draft13
-
To refresh NCBI, rm -rf tax/ncbi. Similarly GBIF and Silva. (Note that GBIF is being updated very infrequently, so refreshing it is sort of a waste of time. Silva is updated about once a year I think.)
-
'make'
-
Result will be in tax/ott/
-
Simpe quality control check: do 'make short-list.tsv' - this will show you taxa have three properties: (1) are used in study OTUs, (2) are deprecated in this version of OTT 2.3, (3) have no replacement taxon id.
To make taxonomies in general:
-
Run Smasher. Command lines arguments are input taxonomies and operations to be performed. See 'nem' and 'ott' targets for examples. Taxonomy specifiers must end in /. Some operations:
--edits
specifies the location of directory full of edit files--ids / specifies a taxonomy from which identifiers will be drawn for reuse (usually the previous version of whatever it is you're building)
--aux / force generation of preottol mapping
Taxonomies can also be specified as Newick strings (not ending in /), for testing purposes.
If you're puzzled by some decision the algorithm has made, it might be helpful to look at the log.tsv file.
