I am looking at enhancers database. And they have position for enhancers as start and end and centre. But for some enhancer they have multiple centres. What do these centers correspond to. I've trying to look around but haven't been able to find an explanation. For example this is a subset of the enhancers file:
chrom start end centre chr1 142618369 142623375 142618762 chr2 220906988 221688903 221093532,221378611,221647234,22162454
At first I thought it referred to centre of enhancer region but the distance to start and end is not symmetric. Can someone provide insight as to what 'centre means' here?
