Possible issue in localZScore function?

[marta-fb]

Hi,

Thanks for this awesome tool!

I'm running regioneR with these 2 functions:

test1 <- permTest(A=file1, B=file2, ntimes=1000, randomize.function=circularRandomizeRegions,count.once=TRUE, evaluate.function=numOverlaps, genome=genome, verbose = TRUE, force.parallel=FALSE, per.chromosone=FALSE)
LocalZscore <- localZScore(pt=test1, A=file1, B=file2)

but when I plot test1 and LocalZscore the zscore for the middle point is different - see below
Test 1 plot:

LocaZscore plot:

I've done the same for other files and they always show the same value in the middle point of the local Zscore plot. The only difference this time is that file2 has 5 million regions.

Can you please help?

Thanks,
Marta
