WebAug 9, 2024 · Finally, as a measure of methylation consistency at gDMRs, we evaluated CpG methylation calls on individual sequence reads from the PBAT libraries for reads with a minimum of 3 CpG positions. In this analysis, ~50% reads in each blastocyst are fully unmethylated, with the remainder being fully or partially methylated. Webmethylation_consistency works for both single-end and paired-end Bismark BAM files, which are auto-detected by default. For paired-end files, all CpGs of both R1 and R2 are …
