Error using predictedAge

[WalterPavicic]

Hi,
I was trying to calculate age using the predictionAge Func, but always get the same error.
Using the example on guides, works:

betas_o <- getBetas(sesameDataGet("EPIC.1.SigDF"), mask=F)
model <- readRDS(url("https://github.com/zhou-lab/InfiniumAnnotationV1/raw/main/Anno/HM450/Clock_Horvath353.rds"))
predictAge(betas_o, model)
[1] 25.7583

But not when running on my data:
Ex1:

sdfs = openSesame(idat_test1s, func = NULL)
beta_1s = openSesame(idat_test1s, BPPARAM = BiocParallel::MulticoreParam(2))
predictAge(beta_1s, model)
Error in predictAge(beta_1s, model) :
Fewer than 10 matching probes left. Age prediction abort.
sum(is.na(sdfs))
[1] 1618794

Ex2:

sdfsR2 = openSesame(idat_test1s, func = NULL)
sum(is.na(sdfsR2))
[1] 1618794
beta_R2_2 = openSesame(idat_test1s, BPPARAM = BiocParallel::MulticoreParam(2), mask=FALSE)
predictAge(beta_R2_2, model)
Error in predictAge(beta_R2_2, model) :
Fewer than 10 matching probes left. Age prediction abort.

I dont know if there is something Im missing?

thanks in adfvance, Walter!

Hi Walter,

I seem to be encountering the same problem. Did you manage to solve it? And how?
