I am very new to these analyses and I’m actually having problems when I want to combine the resulting OTU tables from two different datasets.
I am actually working with two different datasets (no shared samples and each sample with a unique ID) and I would like to know if there exists any command to merge the resulting OTU tables for each of the two datasets if I’ve performed denovo OTU picking. I cannot run both datasets at the same time because of memory and throughput limitations.
Up to now, I’ve only found potential solutions in case of having run reference-based OTU picking but as it is not my case, I do not know how to proceed.
Any idea or suggestion would be very appreciated.
