+The bismark_methylation_extractor output is in the form (tab delimited, 1-based coords):
 
     <seq-ID> <methylation state*> <chromosome> <start position (= end position)> <methylation call>
 
       Methylated cytosines receive a '+' orientation,
     Unmethylated cytosines receive a '-' orientation.
 
-##### The bedGraph output (optional) looks like this (tab-delimited, 0-based start, 1-based end coords):
