Common Use Cases

  1. Creating a bedMethyl table with pileup
  2. Updating and Adjusting MM tags with adjust-mods and update-tags
  3. Summarizing a modBAM with summary
  4. Making a motif BED file with motif-bed
  5. Extracting per-read base modification data into a table
  6. Convert modification probabilities into hard calls
  7. Removing base modification calls at the ends of reads
  8. Narrow analysis to only specific positions with a BED file
  9. Repairing/adding MM/ML tags to reads with clipped sequences
  10. Creating hemi-methylation pattern bedMethyl tables with pileup-hemi
  11. Performing differential methylation scoring with dmr
