actual paired-end distances

05-14-2010, 06:26 AM

Hi,
I have got an Illumina run of paired-end 500 and 100 bases length. A couple of programs want to know minimum and maximum distance. What are reasonable values here?
There is also often the relative orientation of the readpairs, like forward forward or forward backward. Would this be forward backward for a paired-end protocol?
Thanks

The actual distances will depend on your library prep.

At least some aligners will infer the distance from data; even if not, you can always align in single-end mode (perhaps on a sample of the data), compute the required statistics & then run the full-blown alignment

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.
