</font></div>
<div><font size="4">ft_rejectvisual is not deprecated. As a matter of fact, there has been some recent updates to this function, to make its behavior more robust. Since these changes have passed our internal tests, the new version has made
it into the release version. Unfortunately, this seems to cause you some problems. As of yet, it is not clear whether this now is a genuine bug, or a feature of an inconsistency in your data, which only surfaces now. In order to be able to confirm your problem,
you’d need to give a bit more detail about what you have been doing. Important details to include are some characteristics of the data, and a specification of the cfg that you used as an input to ft_rejectvisual. Also, you couuld try and diagnose the problem
a bit more yourself by using the matlab debugger, which you can use to investigate why the variable info.cfg.ylim seems to have an unexpected number of elements (as the error message suggests).</font></div>

Is ft_rejectvisual function deprecated? How can I solve this error? The version 20191019 is no longer available at the FTP server, but I know it works well because I tested the code with that old version.<u></u><u></u></div>
