| Sample type |
SRA |
| |
|
| Source name |
brains
|
| Organism |
Drosophila melanogaster |
| Characteristics |
developmental stage: 3rd instar larva
tissue: brains
chip antibody: H3K27ac (Active Motif #39133)

| Extracted molecule |
genomic DNA |
| Extraction protocol |
Lysates from embryonic cells or 3rd instar brains were clarified from sonicated nuclei and histone-DNA or Nup-DNA complexes were isolated with specific antibody
Libraries were prepared according to Illumina's instructions for NextSeq® 500/550 High Output Kit v2 (FC-404-2005).

| Data processing |
Raw fastq files were trimmed to remove low quality base calls using Trimmomatic, with parameter "LEADING:3 TRAILING:3 SLIDINGWINDOW:3:3 MINLEN:30".
Trimmed reads were aligned to dm3 using Bowtie2, allowing for only uniquely aligned reads (MAPQ > 10) to be reported.
Duplicate reads and mitochondria reads were removed using Samtools and Bedtools.
Significant peaks were called using MACS2, with parameter "--qvalue 0.05 -m 2 50".
Bedgraphs were generated using the command "bedtools genomecov", library sizes were normalized to 10 million reads per sample.
BigWig files were then converted from bedgraph files using command "bedGraphToBigWig".
Genome_build: dm3
Supplementary_files_format_and_content: bigwig files were converted from bedgraph files, which were generated using Bedtools. Scores were normalized to 10 million reads per sample.
