I have app 70 RNA-seq samples on drosophila. When going through the FastQC, there are three red flags to almost all the samples. I'm new to this field and could anyone tell what was wrong and what I should do (please in some details)? Great thanks!

Short answer .. no need to worry. Proceed with data analysis.

A "failed' flag in FastQC should be considered as a guide. It does not automatically mean that the data is bad.
The GC plot "bulge" may represent bacterial (endo-symbionts) that some drosophila populations have. (This may or may not apply in your case).Last edited by GenoMax; 08-21-2015, 09:08 AM.

NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...-

Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?
Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating...-
