Compare function


I would like to know how the compare function works on the samples? I mean, how MEGAN does the assignment when comparing more than one metagenomic sample.

Many thanks!

There are two comparison modes:

  • in absolute mode, the numbers for each sample are copied to the comparison document.
  • in relative mode, all numbers are scaled to the smallest input sample size and then copied to the comparison document. For example, if sample A has X reads assigned to some node T, and if B is the sample with the smallest size, |B|, then the number reported for sample A on node T is X/|A|*|B|.
