I have
- a biom file with individual samples from QIIME.
- a mapping file with a column containing groups based on which I want to collapse samples
I want to
- convert the biom file into .shared file
- group samples in the shared file according to the description in the column in mapping file
- make a venn diagram
Issues I ran into
- the shared file given by make.shared(biom=*.biom) is empty
- I have no idea how to group multiple samples into one according to mapping file data
