Sentence examples for one assembler from inspiring English sources
In rare cases, high similarity between sequences detected in the Euglossa transcriptomes and the reference sequences allowed for subsequent manual identifications of homologs of the other species only assembled by one assembler.
In addition, an approach that makes use of more than one assembler and then compares the resultant assemblies by looking for shared and therefore potentially more robust contig calls derives an assembly of high confidence in the absence of a reference genome [ 23].
Comparative studies to assess the quality of de novo assemblies are scarce and suggest that assembly quality varies widely from one species to another and from one assembler to another [ 28].
These constitute the highCA, while those with evidence from only one assembler and the singletons are the lowCA.
If only one assembler had to be used because of time or resource constraints, we would currently recommend Newbler 2.5 overall.
In contrast, a pre-release version of Newbler 2.5 was identified as the joint top performing assembler, with further improvements being obtained through the concurrent use of more than one assembler.
For each species, all annotations with a completeness and contiguity ≥ 95%% in at least one assembly of each assembler (see Additional file 1: Table S1 for differences in assemblies) were extracted, translated to the corresponding amino acid sequences and validated via BLASTp homology searches against the Refseq proteins.
This can be improved in future versions of the assemblers that can fill gaps using paired-end data anchored on one side on single-copy sequences.
Table 3 shows contig size statistics on one dataset for all assemblers tested.
It is suggested that when using the registers with ARM development tools such as the ARM assembler, one can use either uppercase or lowercase to specify the register to be used.
We are aware of only one de novo assembler designed to integrate Sanger and NGS data, called Forge (Diguistini et al., 2009).
