The error indicates an issue with the links between assays.
pe
QFeatures
object?sessionInfo()
. Are you using the latest versions of the packages? I am following the vignette example from https://statomics.github.io/msqrob2Examples/cptac.html.
I created the pe
QFeatures
object with:
peptidesFile <- msdata::quant(pattern = "cptac_a_b_peptides", full.names = TRUE) ecols <- MSnbase::grepEcols(peptidesFile, "Intensity ", split = "\t")
pe <- readQFeatures( table = peptidesFile, fnames = 1, ecol = ecols, name = "peptideRaw", sep = "\t" )
My packages should be latest version as I run update.packages()
before running the example.
My sessionInfo()
is:

Thanks for the quick response, is there anything I'm missing for this to work?
This is likely due to an outdated version of the vignette. Please refer to the up-to-date version on the Bioconductor website: https://bioconductor.org/packages/release/bioc/vignettes/msqrob2/inst/doc/cptac.html
I will update the msqrob2Examples website so it refers to the Bioconductor vignette.
Essentially what you should do is use the filterFeatures()
function from QFeatures to filter the pe
object.
Thank you! The new vignette examples worked. The example vignette on your github repo: https://github.com/statOmics/msqrob2 refers to the old examples and should probably be updated!
I'm can not get the msqrob2 example "cptac spike-in study" to run properly. The normalize code snippet:
pe <- normalize(pe, i = "peptideLog", method = "quantiles", name = "peptideNorm")
Gives me the following error:
Error in .checkLinksInHits(al@hits, object[[al@name]], direction = "to") : @hits contains links that point to missing features
Can you help me with this error?
