Chart visualization for the metagenomic and genomic analysis tools AMPHORA2 and AmphoraNet

AmphoraVizu can visualize outputs generated by the metagenomic and genomic analysis tool AMPHORA2 or its webserver implementation AmphoraNet.

AMPHORA2/AmphoraNet output: [?]Select an AMPHORA2/AmphoraNet output file.
Lowest taxonomic rank: [?]Select the lowest taxonomic rank you are interested in.
Chart type:
Show advanced options
[?]The Column Chart shows the distribution of phylotypes for each marker gene.
The Pie Chart shows the consensus distribution (averages of the distributions for each phylotype).

Using AmphoraVizu step by step

  1. Upload an AMPHORA2 or AmphoraNet output file.
    Sample input file (HMP - buccal mucosa metagenome analysed by AmphoraNet). More input files
  2. Select the lowest taxonomic rank which you are interested in.
  3. You can use the advanced options choose the display mode, the lower bound for the confidence, the average share and the title. There is a link to display these options.
  4. Click the "Visualize!" button. You will see a chart immediately (if it is not too wide to display in miniview). Then click "Magnify" for the magnified chart. You can download a HTML file with the chart as well. Sample outputs: Column Chart, Pie Chart.
