... Representatives in this context meaning “one E. coli sequence that serves as a reference for all reads that are >`n` amount similar”.
You can still use the reads to find SNP variants or something (it might give you more resolution between specific gene sequences), but whether this is needed or n ...

... Looking at that code, it is mainly extracting flanking sites from annotated genes. While this is broadly addressing the goal, this should not be confused with finding *bona fide* promoter sequences, merely the regions where they would actually be found.
I say this just in case someone in future com ...

... You could try the following:
Set the locale settings and the `locale-gen` tool:
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
locale-gen en_US.UTF-8
If that fails, try setting the locales to `LC_ALL=C perl`. If this succeeds it will likely be due to having your local machine (the ...

... I think there may be some residual confusion, but if we're all on the same page, it does sound like a pangenome analysis problem.
If you use a metagenome-aware assembler, to retrieve representatives of every genome in each of your samples, you can then run them through an annotator such as `prokka` ...

... I think the assemble and remap approach is fine (this is how you'd do transcriptomics). However, since you're only getting once assembly per set of reads for any given genome, I think what you may need to try is a very strict assembly (few if any mismatches allowed). This is then treated as a refere ...

... Are you interested in all variants separately, or are you intending to threshold some similarity scores?
i.e. how different can the sequence be in different mutants and strains before its no longer 'the same gene'.
Can you also tell us how you assembled all the genomes? I think this is a more sub ...

... What you're describing is a `pangenome` study really I think.
Are you really interested in actual frequency of the gene, or just in how many organisms in the same have it (and/or have it more than once)?
i.e. if there's a billion *E. coli*'s in your sample, do you want to know if there are 2 billi ...

... Can you explain a bit further? There may be some terminology confusion here.
Firstly, what exactly do you mean by depth/abundance of genes? Is this copy number of the genes, or number of reads corresponding to those sequences etc. "Depth" of gene coverage would only really make sense in the context ...
