Different errors in importing TDT and Blackrock files.

[00Ziling]

Hi!
I'm starting to work with SpikeInterface and want to use it to process data recorded from TDT system and Blackrock system. I'm having issues reading both the TDT and Blackrock files. I've checked the issues part here to try to find the solution of it. However, I couldn't fix it so far. Could you please help me with it? Thanks!

There is my code and error information for the TDT data:

And the code and error information for the Blackrock data:

Do you have data that you can share with us so we can test?

For TDT the folder that you are using does not seem to contain the corresponding file.
Blackrock takes a file path not a folder path.

Hi! I am also experiencing problems trying to load our tdt files. I didn't observe this behavior when using from neo.rawio import TdtRawIO

After investigating a little more I found that the loader is asking for the .tev file
