GUI recordings taken with GUI v0.6.1 cannot be read with `open ephys python tools`

[lillysanchez]

I made a recording with OpenEphys GUI v0.6.1, but I can't read the recording with the current master of the open ephys python tools. The issue is that there is no continuous or event data being read. This is despite the presence of this data in the folder structure.

The error trace is:

Traceback (most recent call last):

Hi Lilly,

We have a separate branch of code for v0.6.x: https://github.com/open-ephys/open-ephys-python-tools/tree/0.6.0

Soon we will make this the default branch, and make it installable via pip.

I'm attempting to use Branch 0.6.0, but it is no longer available on GitHub. I am using open-ephys GUI 0.6.1 but the tool can't read it. The error is the same as above.

Hi Lilly – the main branch is now compatible with data saved by all 0.6.x versions, and is also available on PyPI. If you create a new Python environment and run pip install open-ephys-python-tools, are you able to read the data? If not, what is the error message?
