接下来数据分为两路,原始电信号经过正则化处理后输入Signal Feature Module,利用多层CNN提取信号特征,该结构借鉴了GoogleNet网络中的Inception单元;序列特征(即从参考基因组上比对得到的核苷酸序列信息)输入Sequence Feature Module,该模块利用3层的双向LSTM层提取序列特征信息。最终序列特征和信号特征信息拼接后输入Classificatio...
-b：记录串联重复序列的位置信息标准文件，包含4列信息：chromosome；start_position；end_position；repeat_unit_sequence *需要注意的是bed文件中起始位置和终止位置 -c：使用CPU数 -o：输出目录 结果图中的两种颜色表示不同的allele；横坐标表示不同的重复次数，纵坐标为每种类型repeat对应的测序reads数。具体的重复...
The base calls are mapped to a genome or transcriptome reference and then the raw signal is assigned to the reference sequence based on an expected current level model.纳米孔读取产生的电流信号水平数据称为squiggle。通过basecalling后得到的reads信息相比于参考序列可能存在一定的错误,因此重新将squiggle到...
Examples of nanopore sequencers include ciswells, transwells, and nanopores that fluidly connect ciswells and transwells. In one embodiment of the sequencer, the modified electrolyte (comprising the electrolyte and the cationic complexing agent) is present in the ciswell, or in the transwell, or...

. The identity to GRCh38 was estimated as 95.20%. Canu was fourfold slower on the Nanopore data compared to a random subset of equivalent coverage of PacBio data requiring∼62K CPU hours. The time taken by Canu increased when the input was nanopore sequence reads because of systematic error...
