从2022年下半年起,最新的建库试剂盒SMRTbell prep kit 3.0 舍弃了CLR模式,全部采用CCS建库测序模式,所以下机的subreads都要经过CCS算法将subreads去冗余转化为HiFi reads。对于Pacbio Sequel II 平台的用户,下机的subreads数据需要在服务器用SMRTlink软件里的CCS程序 或者 自己运行单独安装CCS软件进行HiFi reads的转换。
CCS 读取的质量评估 为了研究 CCS reads中的少许错误,记录了reads与 GIAB HG002 基准之间的不一致。平均一致性为 99.8%,与 Illumina NovaSeq(2×151 bp reads为 99.9%)和 HiSeq 2500(2×250 bp reads为 99.5%)的短reads相当(补充表 2)。大多数 CCS reads不一致是同聚物(homopolymer )中的插入缺失:3.4% ...
pacbio bax.h5文件处理及ccs计算 1.NCBI文件格式如下: 2.格式转换 (1) bas.h5 -> ccs source /share/nas2/genome/biosoft/smrtanalysis/2.3.0/smrtanalysis/current/etc/setup.sh bash5tools.py --readType subreads --outType fasta /path/to/bas.h5 (2) bax.h5 -> ccs 需要各个文件进行转换并进行...
本研究的技术革新有2个方面:1.运用长读长测序技术,即PacBio/CCS模式,并分别使用S/P1-C1.2, S/P2-C2/5.0, S/P3-C3/5.0三种不同版本测序试剂进行16S全长序列测序比较分析,保证获得了高质量长读长的测序数据;2.采用新的分析算法,即DADA2,此方法成功地鉴定出菌群中存在的单碱基分辨率的ASVs(明显不同于uparse...
PacBio HiFi reads provide both long read lengths (up to 25 kb) and high accuracy (>99.9%) to quickly and affordably generate contiguous, complete, and correct de novo genome assemblies of even the most complex genomes. Read more August 19, 2021 | Metagenomics ...
PacBio第三代单分子测序技术以其超长读长,超高准确度为优势,已经广泛应用于基因组相关研究的各个领域。近期,随着PacBio Sequel System 6.0及V3试剂的发布,读长又有了更大幅的提升,平均读长甚至超过45kb(WGS project),结合CCS测序方式,使得PacBio测序技术在单分子准确度上也有了更进一步的提升。
