Local database paths aren't overridden when running experements

Things I did:

  1. Download complete experiment (including database) from https://www.beat-eu.org/platform/;
  2. Make MYFILE.json file as suggested in BEAT Administrator Guide -- 5.4. Instantiating and Starting a Development System, including my database (Putvein):
{
  "atnt/1": "/remote/databases/atnt",
  "banca/2": "/remote/databases/banca",
  "putvein/1": "/idiap/resource/database/PUT_Vein_Dataset"
}
  1. execute the command:
$ ./bin/django install -v1 --database-root-file=MYFILE.json
  1. Now I am able to index the database (and it works!):
$  ./bin/beat -p prefix db index putvein/1
Indexing database putvein/1...
Indexing database `putvein/1', protocol `palm_L', set `train', output `client_id' -> `prefix/cache/da/79/87/d5a7f67591efa0f9377c7d433bcc3c917d14c4ac23ff5c844059f0af7e.index'
Indexing database `putvein/1', protocol `palm_L', set `train', output `image' -> 
<...>
  1. Finaly, I assume that I could run in point [1] downloaded experiment:
$ ./bin/beat experiments run teodors/teodors/vein_recognition_only_dev/1/putvein-muira-only-dev-100

but I still get the error:

<...>
RuntimeError: File - /remote/dataset/PUT_Vein_Dataset/Wrist/o_001/Left/Series_1/W_o001_L_S1_Nr1.bmp: C++ exception caught: 'file '/remote/dataset/PUT_Vein_Dataset/Wrist/o_001/Left/Series_1/W_o001_L_S1_Nr1.bmp' is not readable'
  1. I am able to run experiment only if I manually override the root folder specified in the putvein/1.json:
    "root_folder": "/idiap/resource/database/PUT_Vein_Dataset",

Isn' t this a bug? It would be logical, that user down't need to override anything manual. Or maybe I have missed something?
