I am having trouble with defining my semi-supervised marker set in the phenoDisco function. I am able to recreate the problem using the example from version 2 of the main paper https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6053703/
Here is the code which will work
library(MSnbase)
library(pRoloc)
library(pRolocdata)
library(pRolocGUI)
extdatadir <- system.file ( "extdata" , package = "pRolocdata" )
csvfile <- dir (extdatadir, full.names = TRUE ,
pattern = "hyperLOPIT-SIData-ms3-rep12-intersect.csv" )
hl <- readMSnSet2 (csvfile, ecol = 8: 27 , fnames = 1 , skip = 1 )
fvarLabels (hl)[ 1: 3 ] <- c ( "uniprot.accession" , "uniprot.id" , "description" )
fvarLabels (hl)[ 4: 6 ] <- paste0 ( "peptides.expt" , 1: 3 )
fData (hl)[ 1: 4 , c ( 1: 2 , 4: 6 )]
pData (hl)$ Replicate <- rep ( 1: 2 , each = 10 )
pData (hl)$ Tag <- sub ( "\\.1$" , "" , sub ( "^X" , "" , sampleNames (hl)))
expinfo <- dir (extdatadir, full.names = TRUE ,
pattern = "hyperLOPIT-SIData-fraction-info.csv" )
fracinfo <- read.csv (expinfo, row.names= 1 , skip = 2 ,
header = FALSE , stringsAsFactors = FALSE )
pData (hl)$ Gradient.Fraction <- c (fracinfo[, 1 ], fracinfo[, 2 ])
pData (hl)$ Iodixonal.Density <- c (fracinfo[, 4 ], fracinfo[, 5 ])
hl <- normalise (hl, method = "sum" )
hl <- impute (hl, method = "knn" )
mrk <- pRolocmarkers ( species = "mmus" )
hl <- addMarkers (hl, mrk)
hl <- fDataToUnknown (hl, from = "Golgi apparatus" , to = "unknown" )
getMarkers (hl, fcol = "phenoDisco.Input" )
> getMarkers (hl, fcol = "phenoDisco.Input" )

[25] "Cell.Surface.Proteins" "markers"
hl <- phenoDisco (hl, fcol = "phenoDisco.Input" , times = 200 , GS = 60 )
However, if I remove the "markers" feature I get the same error I am getting in my data
> fData(hl) <- fData(hl)[-26]
> hl <- phenoDisco (hl, fcol = "phenoDisco.Input" , times = 200 , GS = 60 )
Error in `[.data.frame`(fData(x), , fcol) : undefined columns selected

This suggests to me that phenoDisco is using the "markers" feature no matter what is requested with fcol.
'markers' is set by pRolocmarkers earlier and is not the same as phenoDisco.Input
> getMarkers(hl,fcol="markers")

Note: in the paper/vignette the phenodisco function is not actually called because it would take a long time to run so the results are loaded in to save time
In my own data I can use the feature name 'markers' and keep going but unless I am missing something that isn't the intended use of fcol.
