Neuralynx Header Error

[dneophytou]

I am trying to import neuralynx data into python using neo. The code I'm running is:
import neo
dirname = (specify directory name)
reader = neo.io.NeuralynxIO(dirname = dirname, filename = (file name in directory))

The error I am getting is "OSError: No matching header open date/time for application {} version Cheetah. Please contact developers."

Hi,
did you try with the new matser ?

[dneophytou]

Hello, Yes I updated the package and am using the latest version. I had previously tried these commands with the older version and it didn’t work, and so I saw another post on GitHub where the suggestion was to update the software. I am still having the same issue since updating.

Hi @dneophytou Can you provide a small test file, so I can check which Cheetah version and header layout you are using? You can provide a file here without making it publicly accessible https://amubox.univ-amu.fr/s/5Cd2BedrfJs9BQf

I have provided a file via that link. The file is titled with my username at the beginning of the file name. Please let me know if you need anything else.

I've already uploaded a sample file, but I've just also uploaded a screenshot of the exact error message I am getting. Not sure if that'll be anymore help, but wanted to include it just in case there's an error that I'm missing. The screenshot is also titled with my username at the beginning.

I opened a PR here #1107 that should fix this issue. Can you confirm?

[dneophytou]

Hi Julia, yes this worked! Thank you so much for your help!

I encountered the same issue today. This is a screenshot of the error.

Also, I noticed that there is a small bug in the line that raise the OSError. I think .format(an, av) is supposed to fill the first {} with an and the second {} with av. However, only the second string after the + calls .format(an, av) in the source code, which is why the error message is weird.
