Sample GSM4209496 Query DataSets for GSM4209496
Status Public on Oct 26, 2020
Title mC_brain_arctic_lamprey
Sample type SRA
 
Source name brain
Organism Lethenteron camtschaticum
Characteristics source: Frozen sample
Extracted molecule genomic DNA
Extraction protocol DNeasy Blood & Tissue kit (Qiagen)
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).
 
Library strategy Bisulfite-Seq
Library source genomic
Library selection RANDOM
Instrument model Illumina HiSeq 1500
 
Data processing CASAVA v1.8.2
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.0.6.8 before methylation quantification with CGmaptools

Supplementary_files_format_and_content: Bisulfite-seq files (CGmap files) are the direct output from BSseeker2/CGmaptools (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).
