# step 1
primerExample <- findPrimer(system.file("extdata", "NBIDE R BF 118.png", package = "cartridges"))
FPexample <- findFP(system.file("extdata", "NBIDE R BF 118.png", package = "cartridges"), primer = primerExample)
# step 2
centeredExample <- centerBFprimer(FPexample, primerExample)
leveledExample <- levelBF(centeredExample$centeredBF)
# step 3
removedExample <- removeCircular(leveledExample)

Areas that are not part of the breechface impression are set to NA. If this is run after levelBF, removing residuals again means that possible values are -510 to 510.
