Hello, having a problem with some code which previously worked with version 11 of STRINGdb but now throws an error with version 11.5:

library(STRINGdb)
string_db <- STRINGdb$new(version="11.5", species=9606, score_threshold=150, input_directory=getwd())

symbol <- data.frame(gene=dat$symbol)
string2symbol <- string_db$map(symbol, "gene", takeFirst=F, removeUnmappedRows=F)

Error in `[.data.frame`(x, r, vars, drop = drop) : 
  undefined columns selected

I can potentially work around it using the aliases file from STRINGdb but I'd rather not have to (9606.protein.aliases.v11.5.txt).

Many thanks for any advice.

Dear Jessica,

You have an old version of the package. STRING v11.5 is enabled starting from version 2.5 of STRINGdb package. You would need to update bioconductor to download the newest package, or you can do it load it directly from the source.

It should have provided better error message, but we cannot update the code for old packages.

Best, Damian.
