Version Compatibility

Reference examples tested with: GenomicRanges 1.54+

Before using code patterns, verify installed versions match. If versions differ:

• R: packageVersion('<pkg>') then ?function_name to verify parameters

If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying.

DMR Detection

"Find differentially methylated regions" → Identify contiguous genomic regions with statistically significant methylation differences between conditions using tiling, smoothing, or kernel-based approaches.

• R: methylKit::tileMethylCounts() + calculateDiffMeth(), bsseq::BSmooth(), DMRcate::dmrcate()
