Both models are identifying the same 16S rRNA sequence. Not sure I follow. So may I please have a follow-up question? Extracted mapped shotgun metagenomic reads to reference genome. I'm hoping to get some help resolving issues of apparent rRNA contamination in RNA-seq data,... Greetings! Hi. ssu_finder gave me ssu_summary table, and bacteria, archaea, and euk table, I checked the bacteria and archaea table, a lot of hits are duplicated, some are the same length, some are not, some are similar. It does this by running bacterial, bacterial, and euk specific SSU HMMs.

About your assembly, did you use SPAdes or metaSPAdes? Having considering this for a while, I still do not understand which you mentioned: Since these 3 models are similar, it is not unusual to have a valid hit to all 3 models. When I try to insert the 16S rRNA gene into the tree. Cc:"473021677"

For the first hit contig, there has an overlap of the first 2 valid hits from ssu-finder. E.coli and Shigella - different species - apparently, have nearly identical 16s. I have used RefineM to filter thedivergent genome properties, Removing contamination based on taxonomic assignments, incongruent 16s in my genome bins.

Is it will be a similar method as what you described in your paper 'Recovery of nearly 8,000 metagenome-assembled genomes substantially expands the tree of life' RefineM does not try to reduce a genome down to a single SSU gene. I cannot figure out how two populations which have quasi-identical 16S (1511/1533 nucleotides matching, 99%) return ANI values of 80.

Great! and Privacy @dparks1134 , appreciate your quick response! I believe CheckM produces another file indicating which of these 3 models produces the highest bitscore.

SPAdes or metaSPAdes for de-novo assembly? It seems that... Use of this site constitutes acceptance of our, Traffic: 2035 users visited in the last hour. Is there anything wrong? Such as in the figure I inserted in the question. CheckM has an SSU finder option. Sorry for so many questions and confusion. I actually end up in your 'good luck with this one' case, as I have 2x300 bp Illumina.
