|
|
|
170 RepeatExplorer2 clustering is a computational pipeline for unsupervised
|
|
|
171 identification of repeats from unassembled sequence reads. The
|
|
|
172 pipeline uses low-pass whole genome sequence reads and performs graph-based
|
|
|
173 clustering. Resulting clusters, representing all types of repeats, are then
|
|
|
174 examined to identify and classify into repeats groups.
|
|
|
175
|
|
|
176 **Input data**
|
|
|
177
|
|
|
178 The analysis requires either **single** or **paired-end reads** generated
|
|
|
179 by whole genome shotgun sequencing provided as a single fasta-formatted file.
|
|
|
180 Generally, paired-end reads provide significantly better results than single
|
|
|
181 reads. Reads should be of uniform length (optimal size range is 100-200 nt) and
|
|
|
182 the number of analyzed reads should represent less than 1x genome equivalent
|
|
|
183 (genome coverage of 0.01 - 0.50 x is recommended). Reads should be
|
|
|
184 quality-filtered (recommended filtering : quality score >=10 over 95% of bases
|
|
|
185 and no Ns allowed) and only **complete read pairs** should be submitted for
|
|
|
186 analysis. When paired reads are used, input data must be **interlaced** format
|
|
|
187 as fasta file:
|
|
|

|
|
|

231 To prepare quality filtered and interlaced input fasta file from fastq
|
|
|
232 files, use `Preprocessing of paired-reads`__ tool.

|

|
|
237 **Additional parameters**
|
|
|
238
|
|
|
239 **Sample size** defines how many reads should be used in calculation.
|
|
|
240 Default setting with 500,000 reads will enable detection of high copy
|
|
|
241 repeats within several hours of computation time. For higher
|
|
|
242 sensitivity the sample size can be set higher. Since sample size affects
|
|
|
243 the memory usage, this parameter may be automatically adjusted to lower
|
|
|
244 value during the run. Maximum sample size which can be processed depends on
|
|
|
245 the repetitiveness of analyzed genome.

248 **Select taxon and protein domain database version (REXdb)**. Classification
|
|
|
249 of transposable elements is based on the similarity to our reference database
|
|
|
250 of transposable element protein domains (**REXdb**). Standalone database for Viridiplantae species
|
|
|
251 can be obtained on `repeatexplorer.org`__. Classification
|
|
|
252 system used in REXdb is described in article `Systematic survey of plant
|
|
|
253 LTR-retrotransposons elucidates phylogenetic relationships of their
|
|
|
254 polyprotein domains and provides a reference for element classification`__
|
|
|
255 Database for Metazoa species is still under development so use it with caution.

|
|
|
259
|
|
|
260 **Select parameters for protein domain search** REXdb is compared with s
|
|
|
261 equence clusters either using blastx or diamond aligner. Diamond program
|
|
|
262 is about three time faster than blastx with word size 3.
|
|
|
263
|
|
|
264 **Similarity search options** By default sequence reads are compared using
|
|
|
265 mgblast program. Default threshold is explicitly set to 90% sequence
|
|
|
266 similarity spanning at least 55% of the read length (in the case of reads
|
|
|
267 differing in length it applies to the longer one). Additionally, sequence
|
|
|
268 overlap must be at least 55 nt. If you select option for shorter reads
|
|
|
269 than 100 nt, minimum overlap 55 nt is not required.
|
|
|
270
|
|
|
271 By default,
|
|
|
272 mgblast search use DUST program to filter out
|
|
|
273 low-complexity sequences. If you want
|
|
|
274 to increase sensitivity of detection of satellites with shorter monomer
|
|
|
275 use option with '*no masking of low complexity repeats*'. Note that omitting
|
|
|
276 DUST filtering will significantly increase running times
|
|
|
277
|
|
|
278
|
|
|
279 **Automatic filtering of abundant satellite repeats** perform clustering on
|
|
|
280 smaller dataset of sequence reads to detect abundant high confidence
|
|
|
281 satellite repeats. If such satellites are detected, sequence reads derived
|
|
|
282 from these satellites are depleted from input dataset. This step enable more
|
|
|
283 sensitive detection of less abundant repeats as more reads can be used
|
|
|
284 in clustering step.
|
|
|
285
|
|
|
286 **Use custom repeat database**. This option allows users to perform similarity
|
|
|
287 comparison of identified repeats to their custom databases. The repeat class must
|
|
|
288 be encoded in FASTA headers of database entries in order to allow correct
|
|
|
289 parsing of similarity hits. Required format for custom database sequence name is: ::
