This is the format of a simple nPath output that I saved on a table called path_out
[HOME, GLOBAL SEARCH: KEYWORD: SEARCH]
[GLOBAL SEARCH: KEYWORD: REFINE]
[PROMO: MOBILERELEASECALEN: 5003224]
[HOME, HOME, HOME]
Below it is my graphgen code but I get an error 'relation "nodes" does not exist'. I know that 'nodes' is not on my table. Please would you tell how I should change my code to graph my nPath output file 'Path_output'? Thanks.
