Description
Hi,
I’m getting the following error when trying to load data recorded with a SpikeGLX version 20240129 using si.read_spikeglx:
NotImplementedError: This meta file version of spikeglx is not implemented
This does not happen when I process the data recorded with a SpikeGLX version 20220101.
Full traceback:
File ".../spikeglx.py", line 65, in SpikeGLXRecordingExtractor.init
...
File ".../spikeglxrawio.py", line 570, in extract_stream_info
raise NotImplementedError("This meta file version of spikeglx is not implemented")
NotImplementedError: This meta file version of spikeglx is not implemented
The error seems to originate from Neo’s spikeglxrawio.py.
Versions I am using are:
-SpikeInterface version 0.102.3
-Neo version 0.14.1.
-Python 3.11.9
-OS: Windows OS 10 pro ver 2009
Here are the headers of functioning and non-functioning metafiles.

How should I proceed?
Is there a workaround, or can I help by providing a sample .meta file for support of this new format?
If you need the .meta file, I can upload it.
Thank you!

Research direction
Read spikeglx.py at the SpikeGLX extractor entry point and Neo's spikeglxrawio.py around line 570, then compare the functioning and failing .meta headers, especially appVersion and the newer fields. Reproduce the failure with si.read_spikeglx and confirm that data recorded with SpikeGLX 20240129 loads successfully without the NotImplementedError.
