Bracken (Bayesian Reestimation of Abundance with KrakEN) is a highly accurate statistical method that computes the abundance of species in DNA sequences from a metagenomics sample.
I am using the kraken2 + Bracken technique route. In kraken2's result file ".k2report ", the reads of one species read around 1000, while in bracken's processed ".braken "file, the reads of that species read around 2000. Is that normal? Why do the reads readings change after processing?
