See config/ for configuration information.

This workflow takes as input a set of protein sequences, clusters them and functionally annotates the clusters' representatives using Eggnog DB. Then, it selects those without KO annotations ("hypothetical proteins"), aligns them with hhblits against Uniclust30, and finally, it aligns the resulting MSA against PDB70.

Decompress selected_seqs_by_size.tar.gz and use that path in the config file (already set).

To see the commands being executed (-p) without an actual execution of the workflow, use -n. -r prints the "reason" for execution of each rule.

snakemake  --cores 16 -r -p -n

--cores N specify the max. number of cores used by the whole workflow, so if a rule has set more cores, it will use no more than N.

Without the -n the workflow will be executed.

All the results will be placed inside /results. The file all_genes_kos.tsv presents a list of all the genes which have one or more KO terms assigned (the rule propagate_annotations propagates the annotations from the cluster representatives to their members). That file then is used to build a new table, compatible with ko_mapper.py, which will produce 3 files:

• {prefix}_module_completeness.tab
• {prefix}_heatmap.pdf
• {prefix}_barplot.pdf

The rules.pdf represents the DAG of this workflow, but it doesn't include the rules related to hhblits, because those rules depend on a checkpoint rule. The rules not included in the DAG visualization still are executed, this has to do with the way snakemake works and computes the DAG beforehand, it isn't a bug.
