For the reading framework, the interviewees agreed that the cognitive pyramid in the theoretical framework provided a sound basis to distinguish reading abilities between levels.
For cognitive abilities, five parameters were selected to describe reading verb, goal, text type, topic, and language, among which the first three are essential to every descriptor while the last two are added if the compulsory elements fail to distinguish reading abilities between levels.
Meta-Velvet and Meta-IDBA can distinguish reads from different species by partitioning the de Brujin graph based on k-mer coverage and separately assemble each sub-graph.
ISOpure is, however, currently unable to take advantage of data on somatic genetic variants that may help to distinguish reads from normal and tumor RNA.
Computational subtraction of the reads is then carried out, in which HPV-aligned reads are retained using Picard Tools and further processed using UNIX shell program to distinguish reads mapping to different HPV types.
This will require preservation of the identity of the transcribed strand to distinguish reads from overlapping transcripts (which can be accomplished using a modification of the TSEQ protocol) and longer read lengths and/or paired end reads for the transcriptomes will be necessary to link all of the pieces together.
Given a specific genome of interest, a variant-size and a k-mer size, the power to detect variants was modelled, interestingly the authors noted that without a reference, it was difficult to distinguish read errors and repeats from genuine SNPs.
Our approach avoided the problem associated with the AutoSNP approach, i.e., false SNP calls caused by differential or biased allelic expression, and adopted the advantage of the separate subgenome alignment approach, i.e., use of subgenome-specific SNPs to distinguish reads from the two subgenomes, which makes it possible to more confidently call a potential varietal SNP (Table 3).
Only reads with under 384 CALs are subsequently evaluated by the powerful gapped local alignment algorithm, which distinguishes reads with identical mapping to multiple locations versus reads with a best matched location.
This includes the contig-guided PE read alignment against the reference genome resulting in a larger number of alignable reads, and thus a more complete de Bruijn graph (Fig. 2B), as well as the reduction of branched paths in the graph by distinguishing reads from different repetitive regions (Fig. 2C and D).
By mapping the chromosome 8 HPV-genomic fusion transcripts onto the DNA sequence, we distinguished read-through and spliced transcripts resulting from the two independent HPV-18 genomic fragment copies, and we also detected multiple alternative splicing events (Fig. 5d).
