# Astrocyte RNASeq Workflow Package
## Workflow SOP
This SOP describes the analysis pipeline of RNA sequencing data. This pipeline includes (1) quality control, (2) variant calling analysis, (3) identification of fusion genes, and (4) statistical analyses of gene expression and isoform expression. The result R data of the statistical analysis can be visualized using a custom R shiny service.
For each file this workflow:
1) Trim the ends of sequences with remaining adapter or quality scores < 25. Remove any sequence less than 35bp after trimming, then generate a file for capturing information about how many sequences were trimmed.
2) Trimmed Fastq files are aligned to the selected reference genome using HiSAT2 (Kim et al. 2015) or STAR (Dobin et al. 2012)
3) Marks Duplicates using SAMBAMBA
4) Features (genes, transcripts and exons) are counted using featureCounts (Liao et al 2014) and StringTie (Pertea et al. 2015) using the Gencode feature table(Harrow et al. 2012)
5) Basic pairwise differential expression analysis is performed using EdgeR (Robinson et al. 2010) and DESeq
6) Abundances of transcripts are calculated using ballgown (Frazee et al. 2014)
7) Identify gene fusions or fused transcripts using STAR-Fusion.
## Workflow Parameters
fastq - Choose one or more RNASeq read files to process.
genome - Choose a genomic reference (genome).
stranded - If a stranded library is created, please select the appropriate protocol to ensure strand specific analysis
markdups - The default is to remove duplicates, you can skip this function.
pairs - Indicate if this is paired-end or single-end sequencing data
dea - Perform Differential Expression analysis, please skip if there are < 2 sample groups
geneset - Select a set of known genesets for pathway analysis
fusion - Perform Gene Fusion Identification
design - This file matches the fastq files to data abot the sample
The following columns are necessary, must be named as in template and can be in any order:
SampleID
This ID should match the name in the fastq file ie S0001.R1.fastq.gz the sample ID is S0001
Note: SampleID shouldn't start with numbers ie 10C should be changed to S10C
SampleName
This ID can be the identifier of the researcher or clinician
SubjectID
Used in order to link samples from the same patient
SampleGroup
This is the group that will be used for pairwise differential expression analysis
FqR1
Name of the fastq file R1
FqR2
Name of the fastq file R2
There are some optional columns that might help with the analysis:
Tissue
Gender
CultureDate
SequenceRun
Organism
CellPopulation
Treatment
GeneticFeature (WT or KO)
Race
Ethnicity
Age

7) Identify gene fusions or fused transcripts using STAR-Fusion.
8) Identify coding variants:
a) Using GATK, repair the format problem of input BAM file, (2) add read group information, (3) handle N-split mapping of reads caused by RNA splicing, (4) base quality score recalibration (BQSR): detect systematic errors made by the sequencer when it estimates the quality score of each base call and build a model of covariation based on the data and a set of known variants, then adjust the base quality scores in the data based on the model.
b) Detect variants using SAMTOOLS with mapping quality >= 50 and base calling quality >= 20.
c) Detect low frequency variants using SAMTOOLS with variant allele fraction > 0.01 and depth > 50 and has been previously identified.
d) Detect variants using SpeedSeq
e) Detect variants using GATK
