 annot <- read.csv("ExpDesign.csv", header=TRUE)

 raw <- MaxQtoMSstatsFormat(evidence=infile, 

+                            annotation=annot, 
+                            proteinGroups=proteinGroups1)
Error in MaxQtoMSstatsFormat(evidence = infile, annotation = annot, proteinGroups = proteinGroups1) : 
  object 'feaMeasurements' not found

I have looked at my MaxQuant Protein Groups file and there is no such column as feaMeasurements, should that column be in the annotation file instead ?

I am having the same problem, even though I am using the example files MSstats_material posted by MeenaChoi on GitHub.

I suspect a typo somewhere  because there is an argument actually called fewMeasurements. So the function MaxQtoMSstatsFormat() is expecting fea- where it should expect few-.
