if isinstance(config['param_baseline'], str):

When the App is run locally, this configuration is not an issue, but on Brainlife when you define the parameter, it must be either a STRING or NUMBER. So , a NUMBER, a BOOLEAN, or an ENUM.
Case when a parameter is either a str or a float/int
When a parameter can be both a str or a float/ int, we registered it as a STRING on BL, and then we convert it as into a float or int.
But we must be careful: we only want to convert a str into float/int when the App runs on BL. For instance the parameter param_filter_length can be “auto”, a str with the duration in s, or ms, or a int. So to be sure that the conversion into float happens only on Brainlife and only when the user does want to use a float:
| Code Block |
|---|
if config['param_filter_length'] != "auto" and config['param_filter_length'].find("s") == -1:
config['param_filter_length'] = int(config['param_filter_length']) |
Case when a parameter is either a str or a bool
When a parameter can be both a str or a bool, we registered it as a STRING or ENUM on BL (either way, it is considered as a str), and then we convert it into a bool.
For instance the parameter param_proj can be “delayed”, or a bool. So, we registered it as an ENUM parameter and convert "True” and “False“ into a bool:
| Code Block |
|---|
if config['param_proj'] == "True":
config['param_proj'] = True
elif config['param_proj'] == "False":
config['param_proj'] = False |
