I would like to extract the individual genes from a genomic dataset but when I use genemap it automatically translates to peptides. Is there a way to keep this in nucleotide format?

The commands I’m using are below:

nextclade   
–in-order   
–input-fasta data/DENV1\_NC/dengue\_denv1.fasta   
–output-tsv output/nextclade.tsv   
–input-dataset data/DENV1\_NC   
–output-tree output/nextclade.auspice.json   
–output-dir output/   
–output-basename nextclade

Hi @Rhys1234,

Sorry for the late reply.

Nextclade does not write genes in nucleotide format, so currently you would need to extract them yourself, based on alignment (`--output-fasta`) and genemap.
