Error if GRangesList has names about lola HOT 2 OPEN

I'm not sure why that would happen...you're suggesting throw away all names all the time? This appears to be only setting names if they aren't set.

it would be helpful if you paste the text of the error...

Error:

Error in bmerge(i, x, leftcols, rightcols, roll, rollends, nomatch, mult, :
Incompatible join types: x.dbSet (factor) and i.dbSet (integer). Factor columns must join to factor or character columns.

When loading the LOLA region databases, the regionDB$regionGRL names are NULL by default so the function works. When regionDB$regionGRL has names that are not NULL the function errors. I think the problem comes from trying to merge based on columns of different classes (the merge in line 175): scoreTable = scoreTable[annotationDT]. In the first case (names are NULL), the class of both columns that are merged is integer. In the second case, the class of one column is integer and the other is factor (the regionGRL names).

Example:

dbPath = system.file("extdata", "hg19", package="LOLA")
regionDB = loadRegionDB(dbLocation=dbPath)
data("sample_universe", package="LOLA")
data("sample_input", package="LOLA")
names(regionDB$regionGRL) = paste0("dbGR", seq_along(regionDB$regionGRL))

res = runLOLA(userSets, userUniverse, regionDB, cores=1)
