Just some quick questions…
Extracting LFP data in Visual Behavior - Neuropixels July 2022
I wanted to extract LFP data from the new dataset (Visual Behavior - Neuropixels July 2022) but I can’t find any related method.
According to the tutorial from the previous version (Visual Coding - Neuropixels October 2019), we can use .get_lfp(probe_id) but there is no such method in the brand new dataset.
_I tried to open the NWB session file with HDF view and as far as I searched, I could not find any LFP time series data
Well, is there any method to use LFP data?
Mismatch in probe data
Also, I guess there is a bug in the new dataset while extracting probe descriptions (IMGAE attached) :
output description about probes is different between cache.get_probe_table() and session.probes
Is there any white paper or a released paper about the new dataset?
The first release of this data doesn’t include LFP data. LFP data will come in a release later this year, at which point the LFP columns for the session object will be populated. Sorry for the confusion there.
You’re a little ahead of the game (the data is public for testing purposes, but hasn’t been officially ‘released’ with the accompanying public announcement and documentation). There will be a technical white paper released in the next week.
oh got it, thanks!
recently I saw a tweet about its official release, so are LFP data accessible now?
We plan on releasing the LFP data by the end of this year. We still have some packaging and validation to do before it’s ready to go.
