---------------- HARNESSING OUR INNER ECOLOGY TO TRACK AND TREAT DISEASE ----------------
A virtual course and symposium on the microbiome and its future role in precision medicine | October 15-16, 2020
ISB hosted a series of events in October 2020 that highlighted recent in silico, in vitro, and in vivo advances towards engineering the gut microbiome to resolve complex diseases. These events were virtual and free. The intended audience was graduate students, postdocs, principal investigators, industry scientists, educators, and clinicians from across the globe.

Thanks for sharing this! it was very helpful.
Dear Christian Diener, Thanks a lot for such an informative video presentation. It is a problem solver for me. However, I lost the track before Excercise 2. What is the code just before the Excercise 2> Secondly, can we use this program to analyze our own data?
Thanks for sharing such an informative video.
I wanted to know what things metadata.tsv file contains i.e., the column names?
important question. can we perform QIIME2 analysis in a 24 hour time for 16 samples of roughly 100K reads each.????
Question: At 49:05 you mention that cutting off the first nt´s would be conservative...what exactly do you mean by that ( gerne auch auf deutsch :-) )
And thanks so much for the upload!!!
It means the first nts have normally high quality do just remove barcode & adaper
