Minimum (ir maximum) bam depth/coverage for structural variation analyses

07-05-2017, 05:44 AM

*or maximum

We are studying structural variation in several plant genomes Illmumina pair-end DNA re-sequencing, and noticed that the number of deletions in some samples (PINDEL) drops significantly. After having boldly calculated the depth as

[number of reads] x mean read length / genome size

we noticed that in these samples the depth was way lower (around 10 folds on an average of 50).

I was wondering if there is some lower or higher limit in a sample depth to start considering an adulterated result.

Thanks.

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...
