Description Telomerase-positive HeLa cervical carcinoma cell line
Data processing Base-calling performed by Fasteris SA (CASAVA pipeline v.1.8.2)
50 nt-long sequenced reads were mapped onto the genome sequence of Homo sapiens (hg18 assembly) according to sequencing quality using Bowtie.
For genome-wide enrichment analysis, only reads perfectly matching the human genome were retrieved (one mismatch was nevertheless allowed on low-quality nucleotides using –e 20 option). Redundant reads as well as reads mapping to multiple genomic locations were also discarded.
Enrichment peaks were called using SISSRs v 1.4 (Jothi et al., 2008) with default parameters using input DNA as background. Peaks corresponding to repetitive regions were discarded using BEDTools (Quinlan & Hall, 2010) (satellites 2/3, alpha/beta satellites and ribosomal DNAs genomic positions were retrieved from the UCSC repeatmasker track (http://genome.ucsc.edu/)).
Annotation of the identified peaks as well as peak overlap and motif discovery were performed using HOMER tool suite (Heinz et al., 2010)
Genome_build: NCBI36
Supplementary_files_format_and_content: BigWig files were generated using HOMER tool suite (Heinz et al., 2010) and represent normalized fragment density profile (based on genome-unique unredundant perfectly mapping reads). BED files contain coordinates (chromosome, start and end) of called peaks.
