External Email - Use Caution Hi friends, I have built a wrapper with mne to read and analyze data from the new Medtronic Percept implantable sensing enabled DBS device. The code is published here: [www.github.com/neuromodulation/icn\_perceive](http://www.github.com/neuromodulation/icn_perceive)\<[http://www.github.com/neuromodulation/icn\_perceive](http://www.github.com/neuromodulation/icn_perceive)\> Unfortunately, handling correct dates is crucial for conversion into BIDS format. Everything was working fine in January. Now I have installed the code on a new machine and it creates the following issue: raw = ephys.mne\_import\_raw(raw\_data.values.transpose() / 100000, list(raw\_data.keys()), sfreq=sfreq,    ...: ch\_types='seeg', meas\_date=(meas\_date.timestamp(), 0)) raw.info['meas\_date'] Out[38]: (1580223097.0, 0) raw.plot() Traceback (most recent call last):   File "C:\code\Miniconda3\envs\icn\lib\site-packages\IPython\core\interactiveshell.py", line 3331, in run\_code     exec(code\_obj, self.user\_global\_ns, self.user\_ns)   File "\", line 1, in \     raw.plot()   File "C:\code\Miniconda3\envs\icn\lib\site-packages\mne\io\base.py", line 1378, in plot     show\_scalebars=show\_scalebars, verbose=verbose)   File "\", line 21, in plot\_raw   File "C:\code\Miniconda3\envs\icn\lib\site-packages\mne\viz\raw.py", line 336, in plot\_raw     inds += [pick\_types(info, meg=t, ref\_meg=False, exclude=[])]   File "C:\code\Miniconda3\envs\icn\lib\site-packages\mne\io\pick.py", line 383, in pick\_types     exclude = \_check\_info\_exclude(info, exclude)   File "C:\code\Miniconda3\envs\icn\lib\site-packages\mne\io\pick.py", line 295, in \_check\_info\_exclude     info.\_check\_consistency()   File "C:\code\Miniconda3\envs\icn\lib\site-packages\mne\io\meas\_info.py", line 693, in \_check\_consistency     % (prepend\_error, repr(self['meas\_date']),)) RuntimeError: info["meas\_date"] must be a datetime object in UTC or None, got "'(1580223097.0, 0)'" raw.info['meas\_date']=None raw.plot() Out[41]: \
Now if I try to use the datetime object, the following error occurs: raw = ephys.mne\_import\_raw(raw\_data.values.transpose() / 100000, list(raw\_data.keys()), sfreq=sfreq,    ...: ch\_types='seeg', meas\_date=meas\_date) C:\Program Files\JetBrains\PyCharm Community Edition 2019.3\plugins\python-ce\helpers\pydev\_pydevd\_bundle\pydevd\_thrift.py:321: RuntimeWarning: Could not get size for self.info   value = format % v raw.plot() Traceback (most recent call last):   File "C:\code\Miniconda3\envs\icn\lib\site-packages\IPython\core\interactiveshell.py", line 3331, in run\_code     exec(code\_obj, self.user\_global\_ns, self.user\_ns)   File "\", line 1, in \     raw.plot()   File "C:\code\Miniconda3\envs\icn\lib\site-packages\mne\io\base.py", line 1378, in plot     show\_scalebars=show\_scalebars, verbose=verbose)   File "\", line 21, in plot\_raw   File "C:\code\Miniconda3\envs\icn\lib\site-packages\mne\viz\raw.py", line 336, in plot\_raw     inds += [pick\_types(info, meg=t, ref\_meg=False, exclude=[])]   File "C:\code\Miniconda3\envs\icn\lib\site-packages\mne\io\pick.py", line 383, in pick\_types     exclude = \_check\_info\_exclude(info, exclude)   File "C:\code\Miniconda3\envs\icn\lib\site-packages\mne\io\pick.py", line 295, in \_check\_info\_exclude     info.\_check\_consistency()   File "C:\code\Miniconda3\envs\icn\lib\site-packages\mne\io\meas\_info.py", line 693, in \_check\_consistency     % (prepend\_error, repr(self['meas\_date']),)) RuntimeError: info["meas\_date"] must be a datetime object in UTC or None, got "'datetime.datetime(2020, 1, 28, 15, 51, 37)'" C:\Program Files\JetBrains\PyCharm Community Edition 2019.3\plugins\python-ce\helpers\pydev\_pydevd\_bundle\pydevd\_thrift.py:321: RuntimeWarning: Could not get size for self.info   value = format % v Any help is very much appreciated!

External Email - Use Caution hi Julian, can you make sure the meas\_date you pass as datetime object as a time zone defined and that it's UTC? you use for a datetime something like tz=timezone.utc HTH Alex -------------- next part -------------- An HTML attachment was scrubbed...
