high-throughput sequencing reads. Cleaning your data in this way is often required: Reads from small-RNA sequencing contain the 3’ sequencing adapter because the read is longer than the molecule that is sequenced, such as in microRNA, or CRISPR data, or Poly-A tails that are useful for pulling out RNA from your sample but often you don’t want them to be in your reads. Cutadapt_ helps with these trimming tasks by finding the adapter or primer sequences in an error-tolerant way. It can also modify and filter reads in various ways. Cutadapt searches for the adapter in all reads and removes it when it finds it. Unless you use a filtering option, all reads that were present in the input file will also be present in the output file, some of them trimmed, some of them not. Even reads that were trimmed entirely (because the adapter was found in the very beginning) are output. All of this can be changed with options in the tool form above. The tool is based on the **Open Source** Cutadapt_ tool. See the complete `Cutadapt documentation`_ for additional details. If you use Cutadapt, please cite *Marcel, 2011* under **Citations** below. ------------------- **Inputs** ------------------- Input files for Cutadapt need to be: - FASTQ.GZ, FASTQ.BZ2, FASTQ or FASTA To trim an adapter, input the ADAPTER sequence in plain text or in a FASTA file e.g. AACCGGTT (with the characters: **$**, **^**, **...**, if anchored or linked). ============================================= =================== **Option** **Sequence** --------------------------------------------- ------------------- 3’ (End) Adapter ADAPTER Anchored 3’ Adapter ADAPTER$ 5’ (Front) Adapter ADAPTER Anchored 5’ Adapter ^ADAPTER 5’ or 3’ (Both possible) ADAPTER Linked Adapter - 3' (End) only ADAPTER1...ADAPTER2 Non-anchored Linked Adapter - 5' (Front) only ADAPTER1...ADAPTER2 ============================================= =================== Below is an illustration of the allowed adapter locations relative to the read and depending on the adapter type: .. image:: $PATH_TO_IMAGES/adapters.svg ------------------- *Example: Illumina TruSeq Adapters* ------------------- If you have reads containing Illumina TruSeq adapters, for example, follow these steps. For Single-end reads as well as the first reads of Paired-end data: **Read 1** In the **3' (End) Adapters** option above, insert A + the “TruSeq Indexed Adapter” prefix that is common to all Indexed Adapter sequences, e.g insert: AGATCGGAAGAGCACACGTCTGAACTCCAGTCAC For the second reads of Paired-end data: **Read 2** In the **3' (End) Adapters** option above, insert the reverse complement of the “TruSeq Universal Adapter”: AGATCGGAAGAGCGTCGTGTAGGGAAAGAGTGTAGATCTCGGTGGTCGCCGTATCATT The adapter sequences can be found in the document `Illumina TruSeq Adapters De-Mystified`_. ----------- **Outputs** ----------- - Trimmed reads Optionally, under **Output Options** you can choose to output * Report * Info file **Report** Cutadapt can output per-adapter statistics if you select to output the report above. Example: *This is cutadapt 1.16 with Python 3.6.4* *Command line parameters: -j 1 --format=fastq -a AGATCGGAAGAGC --info-file=/tmp/tmpX0DlY1/files/000/dataset_21.dat --output=out1.fq --error-rate=0.1 --times=1 --overlap=3 input_f.fastq* *Running on 1 core* *Trimming 1 adapter with at most 10.0% errors in single-end mode ...* *Finished in 0.00 s (1426 us/read; 0.04 M reads/minute).* *=== Summary ===* * Total reads processed: 3* * Reads with adapters: 0 (0.0%)* * Reads written (passing filters): 3 (100.0%)* * Total basepairs processed: 102 bp* * Total written (filtered): 102 bp (100.0%)* *=== Adapter 1 ===* *Sequence: AGATCGGAAGAGC; Type: regular 3'; Length: 13; Trimmed: 0 times.* **Info file** The info file contains information about the found adapters. The output is a tab-separated text file. Each line corresponds to one read of the input file. Columns contain the following data: * **1st**: Read name * **2nd**: Number of errors * **3rd**: 0-based start coordinate of the adapter match * **4th**: 0-based end coordinate of the adapter match * **5th**: Sequence of the read to the left of the adapter match (can be empty) * **6th**: Sequence of the read that was matched to the adapter * **7th**: Sequence of the read to the right of the adapter match (can be empty) * **8th**: Name of the found adapter * **9th**: Quality values corresponding to sequence left of the adapter match (can be empty) * **10th**: Quality values corresponding to sequence matched to the adapter (can be empty) * **11th**: Quality values corresponding to sequence to the right of the adapter (can be empty) The concatenation of columns 5-7 yields the full read sequence. Column 8 identifies the found adapter. Adapters without a name are numbered starting from 1. Fields 9-11 are empty if quality values are not available. Concatenating them yields the full sequence of quality values. If no adapter was found, the format is as follows: #. Read name #. The value -1 #. The read sequence #. Quality values When parsing the file, be aware that additional columns may be added in the future. Note also that some fields can be empty, resulting in consecutive tabs within a line. If the --times option is used and greater than 1, each read can appear more than once in the info file. There will be one line for each found adapter, all with identical read names. Only for the first of those lines will the concatenation of columns 5-7 be identical to the original read sequence (and accordingly for columns 9-11). For subsequent lines, the shown sequence are the ones that were used in subsequent rounds of adapter trimming, that is, they get successively shorter. -------------------- **More Information** -------------------- See the excellent `Cutadapt documentation`_ .. _Cutadapt: https://cutadapt.readthedocs.io/en/stable/ .. _`Cutadapt documentation`: https://cutadapt.readthedocs.io/en/latest/index.html .. _`Illumina TruSeq Adapters De-Mystified`: http://tucf-genomics.tufts.edu/documents/protocols/TUCF_Understanding_Illumina_TruSeq_Adapters.pdf -------------------- **Galaxy Wrapper Development** -------------------- Author: Lance Parsons <lparsons@princeton.edu> ]]></help> <citations> <citation type="bibtex"> @article{marcel_cutadapt_2011, title = {Cutadapt removes adapter sequences from high-throughput sequencing reads}, volume = {17}, copyright = {Authors who publish with this journal agree to the following terms: Authors retain copyright and grant the journal right of first publication with the work simultaneously licensed under a Creative Commons Attribution License that allows others to share the work with an acknowledgement of the work's authorship and initial publication in this journal.
