## This statement initializes and runs the GMQL server for local execution 
## and creation of results on disk. Then, with system.file() it defines 
## the path to the file "DATASET" in the subdirectory "example"
## of the package "RGMQL" and opens such file as a GMQL dataset named "exp" 
## using CustomParser

init_gmql()
test_path <- system.file("example", "DATASET", package = "RGMQL")
exp = read_gmql(test_path)

## The following statement produces an output dataset with a single 
## output sample. The COVER operation considers all areas defined by 
## a minimum of two overlapping regions in the input samples, 
## up to maximum amount of overlapping regions equal to the number 
## of input samples.

res = cover(exp, 2, ALL())

## The following statement produces an output dataset with a single 
## output sample. The COVER operation considers all areas defined by
