unpack requires a buffer of 8 bytes about pyxdf

This looks like your file might be corrupted. Can you load other XDF files normally?

I can read some, but not others. I used Matlab function, and this one actually read in the file, but with this error: got error "MATLAB:matrix:singleSubscriptNumelMismatch" (Unable to perform assignment because the left and right sides have a different number of elements.), scanning forward to next boundary chunk. scan forward reached end of file with no match.

What do you mean by the MATLAB function read in the file? Didn't it throw the error you are mentioning? @tstenner do you know if there is a tool that checks if a given XDF file is valid?

[agleontyev]

In mean that I tried reading this file using Matlab, via the function in xdf-Matlab. Matlab throws an error, but I can see and access the array with stream information, time stamps and time series.

What is the result of pyxdf.resolve_streams() on that file?

@tstenner do you know if there is a tool that checks if a given XDF file is valid?

That was part of a grant application that didn't go through. Maybe XDFBrowser?
