Since version 0.13.0 with Nkululeko you can define all root folders for your databases at one single place.
This is very handy if you work in paralell on several computers, e.g. a development and a deployment environment.

In the [DATA] section of your ini file, you specify the path to the local data root folder file like this:

[DATA]
root_folders = data_roots.ini
databases = ['dataset_1']
...

and then within the data_roots.ini file (you can actually call it what you want), you declare the folders to your databases like this:

[DATA]
dataset_1 = /mypath/d1/
dataset_1.files_tables = ['files']
dataset_2 = ./d2
...

you can add all your data set options that you need in this file:

[DATA]
emodb = /mypath/d1/
emodb.split_strategy = speaker_split
emodb.testsplit = 40
emodb.mapping = {'anger':'angry', 'happiness':'happy', 'sadness':'sad', 'fear':'fright.', 'neutral':'neutral'}
dataset_2 = ./d2
dataset_2.files_tables = ['files_test', 'files_train']

If you define those fields in your experiment ini file, it will have precedence.
