Hi guys! So, I am an undergraduate student in bioinformatics and I am starting to perform and study metagenomics/microbiome analysis.
I have some data generated through Illumina Hi-Seq. My reads vary between 1-151bp. So, below I will explain shortly what I've done by now: - I cleaned my data, by using FastQC on each sample to identify overrepresented sequences. I removed them using Trimmomatic, together with the SLIDINGWINDOW:4:15 option for extra cleaning.
I didn't set any minimum length for my reads, I am assuming that the more data the better BUT I don't know exactly about that. So, there is any minimum read length to perform metagenomic analysis?
Thanks in advance.
