Hello,
I combined several biom files in an analysis in qiita which were sourced from 11 different studies on qiita. However, the biom and metadata both seem to be problematic when I try to load them into R as a phyloseq object. For example, I get this warning with the biom file and when I try to merge it with metadata, not all of them are combined because some of the IDs are different. When I opened the biom file in R, I see that some of the IDs have Xs before their names. Since there are so many samples, it is difficult to figure out which ones are different. When I open the biom file on text editor, though, there are no X’s. I think as the import process, something is going on wrong because I get this warning:
The biom file in text editor does not look like a normal biom file either:
