The pipeline uses low-pass paired-end whole genome + sequence reads and performs graph-based clustering. The resulting + clusters, representing all types of repeats present in the genome, are + then examined to identify those containing circular structures indicative + of tandem repeats. A poster summarizing TAREAN principles and + implementation can be found `here.`__ + + + .. __: http://w3lamc.umbr.cas.cz/lamc/?page_id=312 + + **Input data** + + + The analysis requires **paired-end reads** generated by whole genome + shotgun sequencing. The data should be provided as a single input file in + fasta format with the reads interlaced (see example below). All the pairs + must be complete, i.e. both "forward" and "reverse" sequence reads must be + present. The reads should all be trimmed to the same length. The optimal + size range is between 100 and 200 nucleotides. The number of reads to be + analyzed should not exceed 1x coverage of the genome. Genome coverage + between 0.01 and 0.5x is recommended. The reads should be filtered for + quality. The recommended quality filtering is as follows: each read should + have a quality score >=10 for 95% of the bases, i.e. if your reads are 100 + base pairs long, then a read only passes this quality threshold if 95 + bases have a quality of 10 or higher. Additionally, any reads containing + indeterminate base pairs (indicated as N in the reads) should be removed. + Finally, if either one of the reads in a pair fails to meet the + aforementioned thresholds, **both** sequences should be removed. + example of interlaced input format:: + + >0001_f + CGTAATATACATACTTGCTAGCTAGTTGGATGCATCCAACTTGCAAGCTAGTTTGATG + >0001_r + GATTTGACGGACACACTAACTAGCTAGTTGCATCTAAGCGGGCACACTAACTAACTAT + >0002_f + ACTCATTTGGACTTAACTTTGATAATAAAAACTTAAAAAGGTTTCTGCACATGAATCG + >0002_r + TATGTTGAAAAATTGAATTTCGGGACGAAACAGCGTCTATCGTCACGACATAGTGCTC + >0003_f + TGACATTTGTGAACGTTAATGTTCAACAAATCTTTCCAATGTCTTTTTATCTTATCAT + >0003_r + TATTGAAATACTGGACACAAATTGGAAATGAAACCTTGTGAGTTATTCAATTTATGTT + ... + + + To perform the quality filtering on your fastQ formatted data as described + above, and to interlace your paired-end sequence reads, + please use the `Preprocessing of paired-reads`__ tool. + + .. __: tool_runner?tool_id=paired_fastq_filtering + + + **Additional parameters** + + **Sample size** defines how many reads will be used during the computation. + The default setting of 500,000 reads will enable detection of high copy + number satellites within several hours. For higher + sensitivity the sample size can be increased. Since the sample size affects + memory usage, this parameter may be automatically adjusted to a lower value + during the run. The maximum sample size which can be processed depends on the + repetitiveness of the analyzed genome. This significantly limits the number of reads + that can be analyzed with the TAREAN pipeline. + + **Perform cluster merging**. Families of repetitive elements are + frequently split into multiple clusters rather than being represented as a + single one. If you do not want to merge clusters based on the presence + of broken read pairs, disable this option. + + **Use custom repeat database**. This option allows users to perform similarity + comparison of identified repeats to their custom databases. The repeat class should + be encoded in FASTA headers of database entries in order to allow correct + parsing of similarity hits. + + **Similarity search options** By default sequence reads are compared using + mgblast program. Default threshold is explicitly set to 90% sequence + similarity spanning at least 55% of the read length (in the case of reads + differing in length it applies to the longer one). Additionally, sequence + overlap must be at least 55 nt. If you select option for shorter reads + than 100 nt, minimum overlap 55 nt is not required. + + By default, + mgblast search use DUST program to filter out + low-complexity sequences. If you want + to increase sensitivity of detection of satellites with shorter monomer + use option with '*no masking of low complexity repeats*'. Note that omitting + DUST filtering will significantly increase running times + + **Output** + + A list of clusters identified as putative satellite repeats, their genomic + abundance and various cluster characteristics are provided. Length and + consensus sequences of reconstructed monomers are also shown and + accompanied by a detailed output from kmer-based reconstruction including + sequences and sequence logos of alternative variants of monomer sequences. + + The output includes an **HTML summary** with a table listing all analyzed + clusters. More detailed information about clusters is provided in + additional files and directories. All results are also provided as a + downloadable **zip archive**. Since read clustering results in + thousands of clusters, the search for satellite repeats is limited to + a subset of the largest ones corresponding to the most abundant genomic + repeats. The default setting of the pipeline is to analyze all clusters containing at least + 0.01% of the input reads. Besides the satellite repeats, three other + groups of clusters are reported in the output (1) LTR-retrotransposons, + (2) 45S and 5S rDNA and (3) all remaining clusters passing the size + threshold. As (1) and (2) contain sequences with circular + graphs, their consensus is calculated in the same way as for satellite + repeats. Additionally a **log file** reporting the progress of the + computational pipeline is provided. + + + + +
