Hi,
I'm trying to do a heatmap with relative abundances instead of using the real OTU counts. Any clue how to do it?
Thanks,
Bea.

Hi Bea,
There's a QIIME script, normalize_tables.py which you can use to convert your OTU counts to relative abundance.
You should then be able to make an heatmap using your normalized biom table.
Cheers,
Justine

Hi Justine,
Thanks for the tip. I had a look of the script but I don't really know to convert the OTU counts to relative abundances. I mean, I don't know which argument I might use for it.
-i, --input_path
Path to the input BIOM file (e.g., the output from OTU picking) or directory containing input BIOM files for batch processing [REQUIRED if not passing -l]
-o, --out_path
Output filename for single file operation, or output directory for batch processing [REQUIRED if not passing -l]
-s, --output_CSS_statistics
Output CSS statistics file. This will be a directory for batch processing, and a filename for single file operation [default: False]
-z, --DESeq_negatives_to_zero
Replace negative numbers produced by the DESeq normalization technique with zeros [default: False]
-a, --algorithm
Normalization algorithm to apply to input BIOM table(s). [default: CSS] Available options are: CSS, DESeq2
-l, --list_algorithms
Show available normalization algorithms and exit [default: False]
