<div class="">Hi Karen,</div>

with overloaded, I mean that there are more functions with the same name. isfield is a built-in matlab function, and it typically does not return an error with a specified line (which is opposed to what was suggested by your pasted error message).
<div class=""><br class="">
</div>
<div class="">I think the best way forward, would be to change into the directory of your downloaded fieldtrip version, and then try ft_defaults, after you have typed restoredefaultpath.</div>

<div class="">Thanks for your response! The first part of the error was "Index exceeds the number of array elements (0)." And there were a bunch of warnings before it. What do you mean by overloaded version? I just searched my computer, and it seems that this
might also be a function in eeglab. What do you think I should do in that case? I tried taking eeglab off my path, but I still got the same error. </div>

Hi Karen,<br class="">
<br class="">
The error message you pasted is incomplete it seems, so it is not clear from a distance what went wrong. Do you by any chance have an overloaded version of an isfield.m function on your matlab path?<br class="">
<br class="">
Best wishes,<br class="">
