BWA: Should Sai/Sam sequences processed match

03-19-2013, 01:23 PM

Hi,

After running BWA I get an output like this:

[bwa_sai2sam_pe_core] print alignments... 0.66 sec
[bwa_sai2sam_pe_core] 197538574 sequences have been processed.
[main] Version: 0.6.1-r104

Should the no. of sequences processed match for the sai and sam files?

For both sai files I have the no. of sequences processed at 147913358
For the sam file it is 197538574

I have re-run this but get the same result. For other sai to sam conversions I have run this number seems to match.

Thanks,

Jom

Given your data is PE, there is no reason the number shouldn't match really. Could be pairing messed up. How many reads do you have in each fastq then?

Best,

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.
