Hi, 
I’m now trying to remove chimera sequences on my data. I’m using Vsearch with the default parameters with the Uchime reference data set and I lost almost all of my sequences (ITS2 fungal sequences) from my sample. Its not normal ?  I’m not familiar with all the setting. Can anyone hepl me ?
Thank

Hi Genevieve,
If you send me the parameters you used while running Uchime, I may be able to help you.
