How to set the database of MMS? about irfu-python

[louis-richard]

Dear Zhang Chi,
Indeed the way to setup the database path is different from that used in irfu-matlab. In the current version of pyrfu, you need to pass and extra argument to the mms.get_data() routine (see https://pyrfu.readthedocs.io/en/latest/_generated/pyrfu.mms.get_data.html).
Hope this will help.

Dear Richard,
there are stil some problems in here.
should we revise the data path in config.py?

CONFIG = {"local_data_dir": "F:/MMS/mms_db/data/",
'mirror_data_dir': None, # e.g., '/Volumes/data_network/data/mms'
'debug_mode': False,
'download_only': False,
'no_download': False}

or in the get_data.py?

def get_data(var_str, tint, mms_id, verbose: bool = True,
data_path='F:/MMS/mms_db/data/'):

I have tried both of them, but still no files can be found.

Dear Zhang Chi,
I uploaded the version 2.3.9 to the python index. This new version contains a routine, named mms.db_init, that setup the path in the configuration file (config.json). Hence, you don't need to give the data_path to the mms.get_data anymore.

Besides, if I'm correct you are using a Windows machine, so I think that the problem you are facing may be due to the different path convention on Windows. You should check the path using os.path.normpath('F:/MMS/mms_db/data/') == 'F:/MMS/mms_db/data/'. Note that the new mms.db_init uses os.path.normpath, so in principle you will not face such problem anymore.

Hope this will work fine.

Dear Richard,
it works well now, thanks a lot!
This code will significantly help us to analyze the data!
