Data processing small RNA-seq libraries: basecalled with the instruments RTA (Run time analysis version 1.12.48.0): SCS (PN:RTA DS:Controlling software on instrument VN:1.13.48.0); fastq files were adapter 'AGATCGGAAGAGCACACGTCT' clipped using cutadapt, version 1.0, default settings; after adapter removal, the first and last 4 bases were trimmed (both linkers contain 4 random nucleotides at their respective termini) from sequence as well using HomerTools, version 3.9.
small RNA-seq libraries: reads were mapped with bowtie v0.12.7 to D. mel. genome (dm3) and BigWig files were created with Samtools v 0.1.16 and BedTools v2.16.1

GRO-seq: basecalled with the instruments RTA (Run time analysis version 1.12.48.0): SCS (PN:RTA DS:Controlling software on instrument VN:1.13.48.0); fastq file was adapter' ATCGTATGCCGTCTTCTGCTTGT' clipped using cutadapt, version 1.0, default settings; after adapter removal, the first and last 4 bases were trimmed (both linkers contain 4 random nucleotides at their respective termini) from sequence as well using HomerTools, version 3.9.
GRO-seq: reads were mapped with bowtie v0.12.7 to D. mel. genome (dm3) and BigWig files were created with Samtools v 0.1.16 and BedTools v2.16.1

RNA-seq: basecalled with the instruments RTA (Run time analysis version 1.12.48.0): SCS (PN:RTA DS:Controlling software on instrument VN:1.13.48.0); fastq files containing 2nd mate were reverse complemented and used together with fastq files containing 1st mate as single-end library; N-containing reads were discarded; reads were trimmed to high-quality bases 6-56 using HomerTools, version 3.9 and mapped to genome and transcriptome using in-house developed pipeline.

ChIP-seq: basecalled with the instruments RTA (Run time analysis version 1.12.48.0): SCS (PN:RTA DS:Controlling software on instrument VN:1.13.48.0); reads were trimmed to bases 2-50 using HomerTools, version 3.9; N-containing reads were discarded; smaller than 50nt-long reads were discarded.
ChIP-seq: reads were mapped with bowtie v0.12.7 to D. mel. genome (dm3) and BigWig files were created with Samtools v 0.1.16 and BedTools v2.16.1

DNA-seq: basecalled with the instruments RTA (Run time analysis version 1.12.48.0): SCS (PN:RTA DS:Controlling software on instrument VN:1.13.48.0); N-containing reads were discarded; smaller than 100nt-long reads were discarded; TEs insertions were called using in-house developed pipeline.
Supplementary_files_format_and_content: DNA-seq: file contains coordinates of TEs insertions called in OSC
Supplementary_files_format_and_content: RNA-seq, GRO-seq, ChIP-seq: file contains density coverage of uniquely mapped reads to dm3
Genome_build: dmel_release 5
