New EST Trimming Strategy
[chapter]
2005
Lecture Notes in Computer Science
Trimming procedures are an important part of the sequence analysis pipeline in an EST Sequencing Project. ...
To remedy this drawback, we propose a new strategy, where each phase detects but does not remove its target, leaving this decision to a post processing step occurring after all phases. ...
The software phred has a parameter to turn on this trimming strategy. ...

Trimming and clustering sugarcane ESTs
2001
Genetics and Molecular Biology
In this paper the new trimming and clustering strategies are described in detail and we give the new official figures for the project, 237,954 expressed sequence tags and 43,141 clusters. ...
We therefore redesigned the clustering procedure entirely, including a much more careful initial trimming of the reads. ...
SUCEST data-users were pointing out many problems when we designed and implemented new trimming and clustering procedures. ...

An optimized procedure greatly improves EST vector contamination removal

The modified trimming procedure for SeqClean was also compared with the trimming efficiency of the other two popular programs, LUCY2, and cross_match. ...
In that case, an alternative sampling strategy should be considered. ...

De novo genome sequence assembly of a filamentous fungus using Sanger, 454 and Illumina sequence data
2009
Genome Biology
Abbreviations EST: expressed sequence tag; GA: Genome Analyzer; Gc: Grosmannia clavigera; indel: insertion or deletion; NCBI: National Center for Biotechnology Information; PE: pairedend; QRL: quality ...
We quantified the efficiency of discovering new and useful sequence data, as well as the rate at which the new sequence data covered GCgb1. ...
Because the 454 assemblies also had acceptably low EST-detectable misassembly rates, we concluded that a strategy that combined all three read types would be optimal. ...

A Novel Terminal-Repeat Retrotransposon in Miniature (TRIM) Is Massively Expressed inEchinococcus multilocularisStem Cells

Genome Biology and Evolution
ta-TRIM (taeniid TRIM). ta-TRIMs are only the second family of TRIM elements discovered in animals, and are likely the result of convergent reductive evolution in different taxonomic groups. ...
Future studies of active and inactive ta-TRIM elements could give the first clues on MGE silencing mechanisms in cestodes. ...
Expression of ta-TRIM Elements and the Generation of New Transcripts The EST evidence suggests that in all the analyzed taeniid species, ta-TRIMs are transcribed at very high levels (>1% of all polyadenylated ...

Analysis of slipped sequences in EST projects
2006
Genetics and Molecular Research
The subsequence strategy is better than the suffix strategy, because it is not anchored at the end of the sequence, so it is more flexible to find slippage at the beginning of the EST. ...
We propose three new methods to detect slippage artifacts: arithmetic mean method, geometric mean method, and echo coverage method. ...
Thus, sequence trimming is an important step that must be performed in EST sequencing projects. Slippage is an artifact type that can be found in EST sequences. ...
