@Lychfindel As of #1326 it is now supported.

Looking through the docs again, those formats are quite a bit more complicated. 3Brain does provide some code examples for both types, but I don't know how much work it...

Coming back to this, `EventsBasedSparseRaw` seems quite a bit different from spikes and waveforms. The compressed .brw files only contains sections of raw data, unlike .bxr files, at least as...

> @BptGrm curious if you have an update/workaround for this! I actually do ! Sorry I forgot to update this issue. I haven't found the actual root cause yet, but...

Accidentally found the culprit in neo while trying to implement BRW v4.x compatibility. In [here](https://github.com/NeuralEnsemble/python-neo/blob/ff97327c71c2621a6b3402f96ad3ca82e0798d64/neo/rawio/biocamrawio.py#L168-L181) : ``` def readHDF5t_100(rf, t0, t1, nch): return rf['3BData/Raw'][t0:t1] def readHDF5t_100_i(rf, t0, t1, nch): return...

I tried it out on a fairly large dataset, things end up being slightly slower with MKL than without. I guess for this kind of problem it would make more...

Since I can't directly contribute to the PR, I forked it and make some updates [here](https://github.com/b-grimaud/python-neo/tree/sparse). Opening a separate PR might be a bit messy ? The main improvement is...

Thanks for the update ! It looks like my [initial commit](https://github.com/NeuralEnsemble/python-neo/pull/1446/commits/1d84c9f74594b1486ccc424d62be8d557547fff0) was retroactively included in the thread already.

As you can see here : `Loaded 0 spikes.`, it seems HS2 found zero spikes. Since the `C.spikes` DataFrame is most likely empty, HS2 failed. Either there is something with...

@zm711 Thanks a lot for the clarification ! > What this really means was that the type of `channel_ids` needs to be a list or array and that `channel_ids` itself...
