Question - re: exclusion of taxa

[awaller2]

Hi there, I was wondering if I could use a regular expression in the config file to, for example, download all 18S 'except' those matching trichinella.

Thanks

Unfortunately, it's not possible from the config file, but you can edit line 32 in scripts/sequence_search.R to change the search term to exclude Trichinella based on NCBI's query format.

Another solution is to export the final database as a CSV or excel spreadsheet and filter out Trichinella sequences in excel or other programs.
