| Description |
CRISPR CTRL(4.2)
28617
WT transfected with a CRISPR/Cas9 plasmid lacking an RNA guide strand (non-target); resulting in a cell line with 100% expression of ADAT2 Replicate 4 Lane 2.
RNA-seq (size fractionation) - Fragments between 160bp and 220bp were selected.

| Data processing |
Solexa Illumina HiSeq 2000 small RNA-Seq data was aligned against the human reference genome hg38 with Bowtie2 version 2.2.2 using local alignment, allowing for 1 mismatch in the first 28 bases and using default options.
Soft clipped bases were removed from the aligned reads with the bamutils utility from the NGSutils software version 0.5.7.
In order to account for the repetitive nature of tRNA types across the genome, all reads (including those that could map to more than one position) were considered. However, reads aligning to two or more different tRNA types were identified with Bowtie2 and removed from the analyses in order to only use those reads aligning unequivocally to multiple copies of the same tRNA type. Finally, tRNA copies with a coverage depth below 10 reads at the anticodon position were also removed from the analysis.
Per replicate counts (pooled lanes) over hg38 tRNAs (Genomic tRNA database, http://gtrnadb.ucsc.edu , January 2016) were obtained with the summarizeOverlaps function from the GenomicAlignments package, using options mode=Union, ignore.strand=FALSE.
Genome_build: hg38 (GRCh38)
Supplementary_files_format_and_content: tRNA_gene_counts_hg38_summarizeOverlaps.xls: Excel file contains per sample tRNA gene counts obtained with the SummarizeOverlaps function from the GenomicAlignments package.
