As an example, since unmethylated Cs are read as Ts, extracting methylation from a position with a C->T mutation will cause incorrect results. In such a case, the opposite strand will have an A rather than a G (in the non-variant case, there would be a G regardless of methylation status). MethylDackel tracks the number of non-Gs on the strand opposite of Cs in the reference sequence. If the fraction of these exceeds the `--maxVariantFrac` option, then that position will be excluded from output. To exclude cases where the `--maxVariantFrac` value is exceeded only due to low coverage, the opposite strand must have a depth of coverage of at least `--minOppositeDepth`. Note that the default value for `--minOppositeDepth` is 0, indicating that the variant site exclusion process is skipped. + +Note that if one additionally specifies `--mergeContext`, that a given CpG or CHG will be excluded from output if either of its individual Cs would be excluded given the specified `--minOppositeDepth` and `--maxVariantFrac`. + -----
