bi2013a not downloadable

[toncho11]

The bi2013a is not currently available with MOABB.

It says

aise BadZipFile("File is not a zip file")

BadZipFile: File is not a zip file

I am using the following script to test most of the visual P300 datasets:

from moabb.datasets import bi2013a, bi2014a, bi2014b, bi2015a, bi2015b, BNCI2014008, BNCI2014009, BNCI2015003, EPFLP300, DemonsP300 
from moabb.paradigms import P300

def GetDataSetInfo(ds):
    #print("Parameters: ", ds.ds.__dict__)
    print("Dataset name: ", ds.__class__.__name__)
    print("Subjects: ", ds.subject_list)
    print("Subjects count: ", len(ds.subject_list))
    
    X, y, metadata = paradigm.get_data(dataset=ds, subjects=[ds.subject_list[0]])
    
    print("Electrodes count (inferred): ", X.shape[1])
    print("Epoch length (inferred)    : ", X.shape[2])
    #print("Description:    : ", ds.__doc__)

paradigm = P300()

#not available: bi2013a(), Lee2019_ERP()
for d in [bi2013a(), DemonsP300(), bi2014a(), bi2014b(), bi2015a(), bi2015b(), BNCI2014008(), BNCI2014009(), BNCI2015003(), EPFLP300()]:
    GetDataSetInfo(d)
    print("======================================================================================")

Deleting and recreating the data inside the MNE folder fixes this issue. But I agree this is somehow annoying.

Sorry for the late reply, I tried to reproduce it multiple times without success. I think this was just a corrupted files downloaded on your server. You need to remove and redownload data in that case, unfortunately.

[toncho11]

Yes, that was the case.
We finally figured it out thanks to @gcattan.

Seeing your GetDataSetInfo code, I think two ideas could interest you:

• @jsosulski made a very nice script to visually check P300 datasets, see Visualize all ERP datasets #261 and proposed a sanity check script Sanity check script #184
• we made a collective effort to document these values from datasets (so people don't need to download data to check them): all the information are available in the wiki https://github.com/NeuroTechX/moabb/wiki/Datasets-Support

We are also interested to add automatically these information in the docs, so if you want to propose something, do not hesitate!
