|
| Organism |
Mnemiopsis leidyi |

|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
DNAzol
Genomic DNA was fragmented with a Covaris S2 sonicator to a mean length of 200 bp, then end-repaired, A-tailed, ligated to methylated Illumina TruSeq adapters, bisulfite converted and subjected to 7 cycles of PCR amplification with KAPA HiFi Uracil+ DNA polymerase (KAPA Biosystems).

| Data processing |
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".
Genome_build: Amphimedon queenslandica genome assembly was downloaded from ftp://ftp.ensemblgenomes.org/pub/metazoa/release-40/fasta/amphimedon_queenslandica/dna/Amphimedon_queenslandica.Aqu1.dna.toplevel.fa.gz, Sycon ciliatum genome assembly was downloaded from http://www.compagen.org/datasets/SCIL_WGA_130802.zip, Nematostella vectensis genome assembly was downloaded from ftp://ftp.ensemblgenomes.org/pub/metazoa/release-40/fasta/nematostella_vectensis/dna/Nematostella_vectensis.ASM20922v1.dna.toplevel.fa.gz, Mnemiopsis leidyi genome assembly was downloaded from ftp://ftp.ensemblgenomes.org/pub/metazoa/release-40/fasta/mnemiopsis_leidyi/dna/Mnemiopsis_leidyi.MneLei_Aug2011.dna.toplevel.fa.gz
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.
