 # Bioinformatics Pipelines
 Bioinformatics pipelines are an integral component of next-generation sequencing (NGS). Processing raw sequence data to detect genomic alterations has significant impact on disease management and patient care. Because of the lack of published guidance, there is currently a high degree of variability in how members of the global molecular genetics and pathology community establish and validate bioinformatics pipelines.
 
-## Bioinformatics Analysis of NGS Data
-NGS bioinformatics pipelines are frequently platform specific and may be customizable on the basis of laboratory needs. A bioinformatics pipeline consists of the following major steps:
+## Bioinformatics Analysis of RNA-seq Data
+RNA-seq is a powerful platform for comprehensive investigation of the transcriptome.The General bioinformatics workflow for the quantitative analysis of RNA-seq data includes three parts: 
+- RNA-seq Quality Check; 
+- Quality timming of Adapters;
+- mapping sequencing reads to a reference genome or transcriptome; 
+- quantifying expression levels of individual genes and transcripts; and
+- identifying specific genes and transcripts that are differentially expressed between samples.
 
-### Sequence Generation
+### BASIC WORKFLOW
 
-> Sequence generation (signal processing and base calling) is the process that converts sensor (optical and nonoptical) data from the sequencing platform and identifies the sequence of nucleotides for each of the short fragments of DNA in the sample prepared for analysis. For each nucleotide sequenced in these short fragments (ie, raw reads), a corresponding Phred-like quality score is assigned, which is sequencing platform specific. The read sequences along with the Phred-like quality scores are stored in a FASTQ file, which is a de facto standard for representing biological sequence information
+#### FASTQ Files - RAW Data
+Raw RNA-seq data are typically formatted as **FASTQ** files. **FASTQ** is a text-based format storing the sequences of the reads as well as their sequencing quality. The file is organized in groups of four lines per read as shown below:
+
+> @NB500929:247:HL2TYBGX3:1:11101:25163:1060
+> GATTTGGGGTTCAAAGCAGTATCGATCAAATAGTAAATCCATTTGTTCAACTCACAGTTT
+> +  
+> !’’*((((\*\*\*+))%%%++)(%%%%).1\*\*\*-+\*’’))**55CCF>>>>>>CCCCCCC65
+
+The first line starts with “@” and is followed by a unique sequence identifier, which includes instrument ID (NB500929), run number (247), and flow cell ID (HL2TYBGX3), followed by the numbers specifying the location of the DNA fragment on the flowcell. In the case of paired-end sequencing, two FASTQ files for read 1 and read 2 include the same sequence identifiers plus the read number (1 or 2), which indicates whether the sequence comes from read 1 or read 2 of the DNA fragment. The second line contains the read sequence. The third line starts with a “+” character and can optionally be followed by the same sequence identifier and any additional description. The fourth line encodes the sequencing quality scores for each base, which are coded as individual symbols according to a [coding scheme](https://support.illumina.com/help/BaseSpace_OLH_009008/Content/Source/Informatics/BS/QualityScoreEncoding_swBS.htm)
+
+#### QUALITY CHECK ON RAW DATA
+RNA-Seq has become one of the most widely used applications based on next-generation sequencing technology. However, raw RNA-Seq data may have quality issues, which can significantly distort analytical results and lead to erroneous conclusions. Therefore, the raw data must be subjected to vigorous quality control (QC) procedures before downstream analysis. Currently, an accurate and complete QC of RNA-Seq data requires of a suite of different QC tools used consecutively, which is inefficient in terms of usability, running time, file usage, and interpretability of the results.
+
+[FastQC](https://www.bioinformatics.babraham.ac.uk/projects/fastqc/) provides a simple way to do some quality control checks on raw sequence data coming from high throughput sequencing pipelines. It provides a modular set of analyses which you can use to give a quick impression of whether your data has any problems of which you should be aware before doing any further analysis.
+
+The main functions of FastQC are:
+
+    Import of data from FASTQ files (also accepts BAM and SAM alignment files)
+    Quick overview of any likely sequencing problems
+    Summary graphs and tables to quickly assess your data
+    Export of results as an HTML-based report
+
+FastQC has a really well documented manual page with detailed explanations about every plot in the report.

+#### QUALITY TRIMMING OF ADAPTERS
+Trimming for adaptors and low quality bases is important part of the analysis pipeline for sequencing data. Typically, after you isolate and fragment your RNA sample, adaptors are attached to the ends of the sequences that are needed for sequencing .These adaptors need to be removed from the sequenced reads before downstream processing. An additional step that needs to be taken is removing low quality bases.
+
+Quality trimming decreases the overall number of reads, but increases to the total and proportion of uniquely mapped reads. Thus, you get more useful data for downstream analyses.
+
+There are many tools for trimming reads and removing adapters, such as Trim Galore!, Trimmomatic, Cutadapt, skewer, AlienTrimmer, BBDuk, and the most recent SOAPnuke and fastp.
+
+Trim Galore! is a wrapper script to automate quality and adapter trimming as well as quality control, with some added functionality to remove biased methylation positions for RRBS sequence files (for directional, non-directional (or paired-end) sequencing).

-> Sequence alignment is the process of determining where each short DNA sequence read (each typically <250 bp) aligns with a reference genome (eg, the human reference genome used in clinical laboratories). This computationally intensive process assigns a Phred-scale mapping quality score to each of the short sequence reads, indicating the confidence of the alignment process. This step also provides a genomic context (location in the reference genome) to each aligned sequence read, which can be used to calculate the proportion of mapped reads and depth (coverage) of sequencing for one or more loci in the sequenced region of interest. The sequence alignment data are usually stored in a de facto standard binary alignment map (BAM) file format, which is a binary version of the sequence alignment/map format. The newer compressed representation [Compressed and Reference-oriented Alignment Map (CRAM)] or its encrypted version [Selective retrieval on Encrypted and Compressed Reference-oriented Alignment Map (SECRAM)]6 is a viable alternative that saves space and secures genetic information, although laboratories need to carefully validate variant calling impact if lossy (as opposed to lossless) compression settings are used in generating CRAM (European Nucleotide Archive, CRAM format specification version 3.0; http://samtools.github.io/hts-specs/CRAMv3.pdf, last accessed November 23, 2016) and SECRAM files.

-> Variant calling is the process of accurately identifying the differences or variations between the sample and the reference genome sequence. The typical input is a set of aligned reads in BAM or another similar format, which is traversed by the variant caller to identify sequence variants. Variant calling is a heterogeneous collection of algorithmic strategies based on the types of sequence variants, such as single-nucleotide variants (SNVs), small insertions and deletions (indels), copy number alterations, and large structural alterations (insertions, inversions, and translocations). The accuracy of variant calling is highly dependent on the quality of called bases and aligned reads. Therefore, prevariant calling processing, such as local realignment around expected indels and base quality score recalibration, is routinely used to ensure accurate and efficient variant calling. For SNVs and indels, the called variants are represented using the de facto standard variant call format (VCF; https://samtools.github.io/hts-specs/VCFv4.3.pdf, last accessed November 23, 2016). Alternative specifications exist for representing and storing variant calls [Genomic VCF Conventions, https://sites.google.com/site/gvcftools/home/about-gvcf/gvcf-conventions, last accessed November 23, 2016; The Sequence Ontology Genome Variation Format Version 1.10, https://github.com/The-Sequence-Ontology/Specifications/blob/master/gvf.md, last accessed November 23, 2016; The Human Genome Variation Society, Human Genome Variation Society (HGVS) Simple Version 15.11. 2016, http://varnomen.hgvs.org/bg-material/simple, last accessed November 23, 2016; Health GAfGa File Formats, https://www.ga4gh.org/ga4ghtoolkit/genomicdatatoolkit, last accessed November 27, 2017].

-### Variant Filtering
 
-> Variant filtering is the process by which variants representing false-positive artifacts of the NGS method are flagged or filtered from the original VCF file on the basis of several sequence alignment and variant calling associated metadata (eg, mapping quality, base-calling quality, strand bias, and others). This is usually a postvariant calling step, although some variant callers incorporate this step as part of the variant calling process. This automated process may be used as a hard filter to allow annotation and review of only the assumed true variants.

-### Variant Annotation
+=== Summary ===
 
-> Variant annotation performs queries against multiple sequence and variant databases to characterize each called variant with a rich set of metadata, such as variant location, predicted cDNA and amino acid sequence change (HGVS nomenclature), minor allele frequencies in human populations, and prevalence in different variant databases [eg, Catalogue of Somatic Mutations in Cancer, The Cancer Genome Atlas, Single-Nucleotide Polymorphism (SNP) Database, and ClinVar]. This information is used to further prioritize or filter variants for classification and interpretation.

-### Variant Prioritization
+#### ALIGNMENT
+Once high-quality data are obtained from pre-processing, the next step is the read mapping or alignment.When studying an organism with a reference genome, it is possible to infer which transcripts are expressed by mapping the reads to the reference genome **(genome mapping)** or transcriptome **(transcriptome mapping)**. Mapping reads to the genome requires no knowledge of the set of transcribed regions or the way in which exons are spliced together. This approach allows the discovery of new, unannotated transcripts.
 
-> Variant prioritization uses variant annotations to identify clinically insignificant variants (eg, synonymous, deep intronic variants, and established benign polymorphisms), thereby presenting the remaining variants (known or unknown clinical significance) for further review and interpretation. Clinical laboratories often develop variant knowledge bases to facilitate this process.
-> Some clinical laboratories choose to apply hard filters on called variants on the basis of variant call metadata or from a data dictionary (variant filtering) as a component of the pipeline analysis software. Because its purpose is to hide certain variants from the view of the human interpreter, it is absolutely critical that filtering algorithms be thoroughly validated to ensure that only those variants meeting strict predefined criteria are being hidden from view. Otherwise, the human interpreter may miss clinically significant variants that may result in harming the patient.
