this is the code from the inter_checks.py station-id is not defined in the code: need to be "target_station_id":

station_list = utils.get_station_list(restart_id=restart_id, end_id=end_id)

## read in all the neighbours for these stations to hold ready
all_neighbours = read_neighbours(restart_id=restart_id, end_id=end_id)

## now spin through each ID in the curtailed list
for st, target_station_id in enumerate(station_IDs):
    print("{} {} ({}/{})".format([http://dt.datetime.now](https://t.co/98B1rf6a8L)(), target_station_id, st+1, station_IDs.shape[0]))

    if not clobber:
        ## wanting to skip if files exist
