Visual Behavior - Neuropixels July 2022 LFP data and probe missmatch

[m-abdollahi]

Hi!

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

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 https://raw.githubusercontent.com/m-abdollahi/Stargazzers_Allen_project/main/pics/WHat.png

Is there any white paper or a released paper about the new dataset?

thanks!

Hi @m-abdollahi

1. LFP data has not been released yet for visual behavior neuropixels. There are plans to release this in the future.
2. Thanks for pointing that out. Technically, LFP data exists, which is why the cache.get_probe_table() is reporting metadata about LFP. However, this has not been released yet.
3. A white paper has not been released yet. Technically, the allensdk release of Visual behavior neuropixels happened before the official release.

Hi @aamster Thanks for the feedback, oh got it, thanks! recently I saw a tweet about its official release, so are LFP data accessible now?

@m-abdollahi LFP data was not released with the initial release. There are plans to release it in the future.
