Sample GSM3518746 Query DataSets for GSM3518746
Status Public on Aug 02, 2019
Title plX_HALO_YY1_DBD_DAPseq
Sample type SRA
 
Source name swimming_larva_0h
Organism Amphimedon queenslandica
Characteristics developmental stage: swimming_larva_0h
individuals: individuals from Heron Island
experimental variable: incubated with in-vitro translated AquYY1 DNA binding domain fused to HaloTag
Extracted molecule genomic DNA
Extraction protocol Phenol-chloroform extraction
Genomic DNA was fragmented with a Covaris S2 sonicator to a mean length of 200 bp, then end-repaired, A-tailed, ligated to Illumina TruSeq adapters, incubated with in-vitro translated AquYY1 DNA binding domain fused to HaloTag and affinity purified. The resulting DNA was amplified 20 cycles.

Description RL1403
Data processing Library strategy: DAP-seq
CASAVA v1.8.2
For Bisulfite-seq and TAB-seq, adapters were trimmed using fastp as default, then aligned to the reference genome using Bowtie2 and BSseeker2 with the option --bt2--end-to-end. PCR duplicates were removed using Sambamba v.0.6.6 before methylation quantification with BSseeker2. For DAP-seq and ampDAP-seq, reads where trimmed with fastp and mapped to the genome using bowtie with the parameters "-m 1 -v 1", then peaks where called using macs2 using pIX Halo empty bam as background and parameters "-q 0.05 --down-sample -g 166679601".

Supplementary_files_format_and_content: Bisulfite-seq files (CGmap files) are the direct output from BSseeker2 (https://github.com/BSSeeker/BSseeker2), they contain chromosome position, (1) chromosome (2) nucleotide on Watson (+) strand (3) position (4) context (CG/CHG/CHH) (5) dinucleotide-context (CA/CC/CG/CT) (6) methylation-level = #_of_C / (#_of_C + #_of_T). (7) #_of_C (methylated C, the count of reads showing C here) (8) = #_of_C + #_of_T (all Cytosines, the sum of reads showing C or T in that position). Macs2 xls files are described in https://github.com/taoliu/MACS/blob/master/README.rst.
