#CycloneSEQ
Just had my first experience with CycloneSEQ data and shared my findings in this blog post:
rrwick.github.io/2024/12/17/c...

How does CycloneSEQ compare to @nanoporetech.com? I looked at both read-level and consensus-level accuracy. Check it out!

I was expecting this kind of data and feedback about #CycloneSEQ, the long read sequencing technology developed by #MGI

When publishing the first benchmarking data for a new sequencing technology like CycloneSeq, it's great having @protocolsio.bsky.social to share the protocols in a transparent manner.

And thoughts on the BGI Nanopore sequencer which prompted this:

"CycloneSEQ’s accuracy is not yet competitive with ONT. However, ONT’s accuracy improved dramatically over the course of its history, so I anticipate that CycloneSEQ may follow a similar trajectory."

Oxford Nanopore wins injunction against MGI Tech in Europe
The Unified Patent Court barred MGI Tech from selling its CycloneSEQ sequencing systems across eight European jurisdictions after ruling they infringe two Oxford Nanopore patents.

The other CYCLONESEQ instrument has a single, larger flow cell, presumably the higher throughput version.

Back to CYCLONESEQ, one instrument type seems to have a 2-bay A+B configuration, presumably for the smaller flow cell type.
July 29, 2025 at 9:46 AM
Another bit of info is the CYCLONESEQ technology, very similar in format to Oxford @nanoporetech.com sequencing. They have two size instruments, both similar to the ONT P2 Solo and P2I in size.

And then there are of course the nanopore copycats that will come online now that patents are expiring.

CycloneSEQ, for example.
