How to filter out contaminant features from feature table

HI @Nicholas_Bokulich,

Thank you very much for useful tutorial link. I imported data into qiime2 successfully. I have another problem which is removing features that overlapped between treatment samples and kit and PCR controls samples. I have found a lot discussion on the forum. I was wondering what is the latest suggestions (tutorial) to remove these features?


If you have specific features in mind, see here

Otherwise as you’ve seen from the copious forum discussion, there are lots of questions but few answers. How to filter unknown contaminants from data is a very open area of research. :man_shrugging:

Good luck!
