DADA2 vs Deblur

11-21-2017, 03:25 PM

I noticed at the qiime2 forum someone else asked the same question I have - How do these 2 compare (or perhaps contrast would be better focus?) for output other than faster speed for Deblur? The forum suggested the person ask here at seqanswers, but it doesn't seem like they followed up. Can someone tell me anything about this that would be helpful as I move forward analyzing 16s V3 region amplicons. Thanks!

Hi urchin i just finished comparing DADA2 and deblur and have concluded that DADA2 is the correct decision. We use v3v4 and DADA2 gives 3 to 4 times as much high-quality data in return as deblur.

My thought is deblur is for very short sequences because it was close to DADA2 when i chopped to 100bp like in the deblur paper : but we use the whole v3v4 for better assignment. Perhaps v3 is very short? Otherwise i would recommmend DADA2.

Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems

by SEQadmin2

Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

Cancer Drug Resistance: The Lingering Barrier to Rising Survival

by SEQadmin2

Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

There is no single reason why many patients don’t respond to treatment as expected. Cancer is...

Reply to Nine Things a Sample Prep Scientist Thinks About Before Sequencing

by GATTACAT

Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.
