Hi Yakub,

You can refer to the following MATLAB Answer in which another user had the same issue, i.e., the command “mzxmlinfo” works fine, however, the command “mzxmlread” throws the “Bad subscripting index” error:

The “mzxmlread” command only supports .MZXML files of version specification 2.1 or earlier. This could be potentially causing the error. You can refer to the following documentation to know more about the “mzxmlread” command:

I hope this helps resolve your error.
