How accurate is PacBio?

PacBio is the only sequencing technology to offer HiFi reads that provide accuracy of >99.9%, on par with short reads and Sanger sequencing.

Why does PacBio have high error rate?

PacBio sequencing is expected to produce reads that have errors uniformly distributed across the read (6). ONT sequencing results are especially error prone in homopolymeric regions, mainly due to the design of the nanopore. Furthermore, the accuracy of ONT sequencing depends on the GC content (19).

Is PacBio more accurate than Illumina?

PacBio provides longer read length than Illumina’s short-length reads. It is not worse than short reads for calling SNP/indels, quantifying transcripts. Sounds like PacBio can do whatever Illumina platform can offer.

How accurate is Illumina?

As shown below, a quality score of 20 represents an error rate of 1 in 100, with a corresponding call accuracy of 99%….SBS Technology Overview.

Quality Score	Probability of Incorrect Base Call	Inferred Base Call Accuracy
10 (Q10)	1 in 10	90%
20 (Q20)	1 in 100	99%
30 (Q30)	1 in 1000	99.9%

Do short reads have a high error rate?

PacBio reads typically have a really high error rate (~15% compared with ~0.1% for Illumina.) It will allow assays to produce a more complete readout of all regions in the genome, including those with low mappability with short-reads technologies.”

Is PacBio expensive?

The first (IMHO and the most common reason) is still the cost of both sequencing and the instruments. PacBio sequencing is according the same webpage $115 per Gbp, however at our sequencing center it’s ~$200.

What is PacBio good for?

The highly-contiguous de novo assemblies using PacBio sequencing can close gaps in current reference assemblies and characterize structural variation (SV) in personal genomes. With longer reads, we can sequence through extended repetitive regions and detect mutations, many of which are associated with diseases.

What is error rate in sequencing?

One of the most widely used sequencing techniques is sequencing-by-synthesis. The average error rate of this approach is reported to be 0.1% per nucleotide, most of which are single nucleotide substitutions2.

What is sequence error?

[′sē·kwəns ‚er·ər] (computer science) An error that arises when the arrangement of items in a set, for example, a deck of punch cards, does not follow some specified order.

What does 10X genomics do?

The 10X Genomics technology generates individually barcoded sequencing libraries for hundreds of thousands of nanoliter volume oil droplets using up to 1.7 million different barcodes. Thus, it allows individual long DNA molecules 10X Genomics Chromium Genome Linked-reads principle.
