The Huanglongbing (HLB or Citrus Greening) is a pathogen that attacks citrus species. Whenever we search the NCBI database and download sequences, we rapidly note that the fasta headers contain the following names: Greening,Huanglongbing,Candidatus,liberibacter,asiaticus,americanus,africanus If we have e-probes specific to HLB, these names must be used in the -f argument.
Fasta headers are a headache in Metasim and we are required to remove to avoid the issue of modifying 1000s of entries in the taxon profile. To remove the headers of a multifasta use the following code:
sed "/>/d" target_multifasta.fasta > output_singleheader.fasta
