concatenate_raws produces EDFs files with no output

There are a lot of things going on, let’s try to narrow down the issue a bit.

  1. MNE 1.7.0 has been released, can you please upgrade and see if the problem still persists?
  2. Does the export error also occur with just a single file or only after concatenation?
  3. The number -69964600 might be a digital value and not a physical value, which is why you cannot find it in your data.
  4. Can you show the output of raw.describe() (where raw is the raw data immediately prior to export)?

I am in the process of trying out your provided steps, but for the time being I was just wondering if you can help me understand what these digital values are?

EDF encodes data as 16bit integers, which are mapped to physical values. I am not entirely sure, but I assume that the value -69964600 is a digital value, but without seeing the data it’s difficult to tell.
