Dosage_Compensation

Quality control: FastQC version 1.8.0_20 using default parameters (available at https://www.bioinformatics.babraham.ac.uk/projects/fastqc/)

Low-quality bases trimmed: Trimgalore v. 0.4.4 using -phred 33, -q 20 (available at https://www.bioinformatics.babraham.ac.uk/projects/trim_galore/)

RNA samples were *aligned: *Tophat v. 2.1.1 with -i 10 -I 10000 (TRAPNELL et al. 2012)

annotated transcripts (https://support.illumina.com/sequencing/sequencing_software/igenome.html)

assemble the transcriptomes: Cufflinks v. 2.2.1 default parameters (TRAPNELL et al. 2012).

Normalization: Cuffnorm v. 2.2.1 with default parameters

differential expression: was found using Cuffdiff v. 2.2.1 with default parameters

read counts: HTseq v. 0.6.1pl (Python v. 2.7.8) (ANDERS et al. 2015)

convert .sam files into .bam files and sort the resulting .bam files: Samtools (version 1.3.1) (LI et al. 2009) Scripts can be found at https://github.com/hollygene/Dosage_Compensation/blob/master/assembly_script.sh edgeR (ROBINSON et al. 2010) was used to calculate counts per million, then filtered based on high variance

FPKM: Cuffnorm (TRAPNELL et al. 2012) A homebrew bash script was used to join the FPKM values for each line with the gene attributes file, turn the file into a .csv, remove mitochondrial sequences, and change the chromosome names from Roman numerals to numbers (script can be found at https://github.com/hollygene/Dosage_Compensation/blob/master/DC_workflow_April2017.sh)

R scripts are located at https://github.com/hollygene/Dosage_Compensation/blob/master/DC_workflow_old_MA.Rmd and https://github.com/hollygene/Dosage_Compensation/blob/master/DC_workflow.Rmd

Individual gene analysis

raw count data: HTseq

differential expression analysis: DESeq2 default parameters, FDR of 0.1 https://github.com/hollygene/Dosage_Compensation/blob/master/R/scripts/R_scripts/DESeq2.Rmd

Annotations: TxDb S cerevisiae database (CARLSON M 2015)

Histograms: ggplot2 in the R package (WICKHAM 2016)
