What is RepeatModeler?

Repeatmodeler is a repeat-identifying software that can provide a list of repeat family sequences to mask repeats in a genome with RepeatMasker. Things to consider with this software is that it can take a long time with large genomes (>1Gb==>96hrs on a 16 cpu node).

How does RepeatModeler work?

RepeatModeler uses results from three other programs, RECON, RepeatScout, and Tandem Repeats Finder (TRF) to build a repeat library for an assembly. RepeatScout is good for finding highly conserved repetitive elements, while RECON can find less highly conserved elements.

How do you find repeats in genome?

Rigorous studies of genome sequence repeats involve identifying similar sequence pairs, grouping the related elements to examine their number and distribution within the genome, differentiating repeats of known function from those of unknown function (and genes from nongenes), and unraveling the details of the length.

What is RepeatMasker?

RepeatMasker is a program that screens DNA sequences for interspersed repeats and low complexity DNA sequences. Sequence comparisons in RepeatMasker are performed by the program cross_match, an efficient implementation of the Smith-Waterman-Gotoh algorithm developed by Phil Green.

What is low complexity DNA?

Low-complexity regions are often defined as regions of biased composition containing simple sequence repeats (1). A sequence enriched with imperfect direct and inverted repeats may also be considered as a sequence with low complexity (5).

What do transposable elements do?

A transposable element (TE, transposon, or jumping gene) is a DNA sequence that can change its position within a genome, sometimes creating or reversing mutations and altering the cell’s genetic identity and genome size. Transposons are also very useful to researchers as a means to alter DNA inside a living organism.

What are interspersed repeats in the genome?

noun, plural: interspersed repeats. A type of repeated sequence in which the copies are dispersed throughout the genome and not side by side. Supplement. The repeated sequences occur as multiple copies of nucleic acids in the genome.

How do you cite RepeatModeler?

Please use the following for the RepeatModeler software: Smit, AFA, Hubley, R. RepeatModeler Open-1.0. 2008-2015 www.repeatmasker.org>.

What does low complexity mean in medical terms?

Low Complexity Medical Decision-Making requires only slightly more intellectual energy than straightforward MDM. The acuity of care remains minimal. For example, this level of MDM is required for a level 3 office visit (99213) or a level 3 office consult (99243).

How is RepeatMasker used to screen for repeats?

RepeatMasker is a program that screens DNA sequences for interspersed repeats and low complexity DNA sequences. The output of the program is a detailed annotation of the repeats that are present in the query sequence as well as a modified version of the query sequence in which all the annotated repeats have been masked (default: replaced by Ns).

What are RepeatModeler recon and repeatscout used for?

RepeatModeler is a de-novo repeat family identification and modeling package. At the heart of RepeatModeler are two de-novo repeat finding programs ( RECON and RepeatScout ) which employ complementary computational methods for identifying repeat element boundaries and family relationships from sequence data.

What is the purpose of the repeatscout program?

The purpose of the RepeatScout software is to identify repeat family sequences from genomes where hand-curated repeat databases (a la RepBase update) are not available. In fact, the output of this program can be used as input to RepeatMasker as a way of automatically masking newly-sequenced genomes.

Where can I find the repeatscout source code?

GitHub – mmcco/RepeatScout: The RepeatScout 1.0.5, written by Pevzner et al., source code for browsing. The official release and more information are available at http://bix.ucsd.edu/repeatscout/ Use Git or checkout with SVN using the web URL.
