[…] were subjected to isoform-level clustering by iec algorithm and herein produced consensus sequences of isoform. finally, the isoform sequences were corrected in aid of illumina short reads using lordec tool v0.6 with -k 21, -s 3, and default setting for other parameters., the corrected isoform sequences were aligned against reference genome using gmap aligner v2016-08-24 with the parameters: […]

[…] the libraries as follows. in the case of illumina libraries, exact read duplicates were removed using the ’in silico normalization’ utility from trinity. for pacbio, reads were error-corrected using lordec v0.4.1 based on the two paired-end illumina libraries (table s1). kmers ranging from 19 to 36 were tested for error-correction. we made an effort to assemble intact pacbio reads following […]

[…] software from pacific biosciences that did not exhibit an identifiable poly-(a) tail and 3′ adapter were removed. finally, iso-seq reads were corrected using a hybrid error correction method lordec () against a de bruijn graph constructed from the bulk of rna-seq libraries (approximately 109 of 101 nt paired-end rna-seq reads, see above). these corrected iso-seq reads […]

[…] of iso-seq isoforms is also improved with hiseq short reads []. in this case, certain programs have recently been developed such as pacbiotoca (error correction via celera assembler) [], lsc [], lordec [], and proovread []. pacbio long reads for phage, prokaryotic, and eukaryotic genome sequencing are corrected to 99.9% accuracy by pacbiotoca []. the computation method of lsc applies […]

[…] a custom hybrid strategy (supplementary fig. ). the illumina reads were corrected with bayes hammer within spades v3.1 assembler. corrected illumina reads were used to correct the pacbio reads with lordec v0.2. illumina and pacbio reads were analyzed with spades v3.1, which produced a raw draft assembly. contigs from the draft assembly were merged into scaffolds with successive iterations […]

[…] 3′ primer, and a poly-a tail were further selected for downstream analysis. next, these full-length reads were collapsed into consensus transcripts by ice and quiver in the isoseq_cluster panel. the lordec software was used to correct the sequencing errors in the consensus transcripts using illumina reads as the reference (parameters: -k 19 -s 3). the corrected consensus transcripts […]
