problems with loading the data with the Matlab script

[fabaroni]

I'm trying to use the Matlab code to load the data, but I get an error which seems to be related to datenum8601.m (dnum is an empty array):

Index exceeds the number of array elements (0).

Error in types.util.checkDtype (line 142)
datetime(dnum(1), 'TimeZone', tz, 'ConvertFrom', 'datenum');

Error in types.core.NWBFile/validate_session_start_time (line 470)
val = types.util.checkDtype('session_start_time', 'isodatetime', val);

Error in types.core.NWBFile/set.session_start_time (line 321)
obj.session_start_time = obj.validate_session_start_time(val);

Error in types.core.NWBFile (line 163)
obj.session_start_time = p.Results.session_start_time;

Error in NwbFile (line 15)
obj = obj@types.core.NWBFile(varargin{:});

Error in io.parseGroup (line 69)
parsed = NwbFile(kwargs{:});

Error in nwbRead (line 31)
nwb = io.parseGroup(filename, h5info(filename), Blacklist);

Error in NWBloadDataOfBlock_release (line 29)
nwb = nwbRead([basepath, filesep, NWBsession.filename]);

Error in NWBprepareData_forSession_demo (line 11)
RTRecog_raw, RTRecog_vsQ] = NWBloadDataOfBlock_release( NOsession_toUse, ind, 1,basepath ); %1 mode recog

Error in NWBneural_loopOverSessions_release (line 33)
[paramsForRun, basedirData_forSession,basedirEvents_forSession,brainArea] = NWBprepareData_forSession_demo( basepath,
NOsessionRecog, NOind, paramsIn );

Error in NWBneural_main (line 94)
[totStats,cellStatsAll] = NWBneural_loopOverSessions_release(allSessionsToUse, NWBsessions, basepathData,analysisMode,
paramsInPreset );

So far I'm just trying to load the data from a single session (session 5, as indicated in NWBneural_main.m).

I've tried with a couple of different versions of matlab (R2021a and R2021b) running in Ubuntu.

Thank you for any help, best

It seems this may possibly be an issue with newer versions of Matlab (>2020). We tested on Matlab versions (<2018). Let me look into this!

I'm having the same issue... (Matlab 2020a) Did you find some solution?
