Masking repeats while clustering ESTs

A problem in EST clustering is the presence of repeat sequences. To avoid false matches, repeats have to be masked. This can be a time-consuming process, and it depends on available repeat libraries. We present a fast and effective method that aims to eliminate the problems repeats cause in the process of clustering. Unlike traditional methods, repeats are inferred directly from the EST data, w...

nematode ESTs on the Net

The parasitic nematode expressed sequence tag (EST) project, a collaboration between University of Edinburgh and the Wellcome Trust Sanger Institute in the UK and the Genome Sequencing Center, St Louis, MO, USA, is currently generating sequence information from >30 different species of nematode. Over 400 000 nematode ESTs are now available and at least another 130 000 are planned. Here, an upda...

Selecting for functional alternative splices in ESTs.

The expressed sequence tag (EST) collection in dbEST provides an extensive resource for detecting alternative splicing on a genomic scale. Using genomically aligned ESTs, a computational tool (TAP) was used to identify alternative splice patterns for 6400 known human genes from the RefSeq database. With sufficient EST coverage, one or more alternatively spliced forms could be detected for nearl...

Minimum Factorization Agreement of Spliced ESTs

Producing spliced EST sequences is a fundamental task in the computational problem of reconstructing splice and transcript variants, a crucial step in the alternative splicing investigation. Now, given an EST sequence, there can be several spliced EST sequences associated to it, since the original EST sequences may have different alignments against wide genomic regions. In this paper we address...
