SpLitteR: Diploid genome assembly using linked TELL-Seq reads and assembly graphs

Recent advances in long-read sequencing technologies enabled accurate de novo assembly of large genomes and metagenomes. However, even long and accurate high-fidelity (HiFi) reads do not resolve repeats that are longer than the read lengths. This limitation significantly affects the contiguity of diploid genome assemblies since two haplomes share many long identical regions. To generate telomere-to-telomere assemblies of diploid genomes, biologists use additional experimental technologies, such as linked reads or ultralong Oxford Nanopore reads. In particular, the barcoded linked-reads, generated using an inexpensive TELL-Seq technology, provide an attractive way to bridge unresolved repeats in phased assemblies of diploid genomes.
