Hi Tyler,
<div class=""><br class="">
</div>
<div class="">Thanks for the very clear email describing your problem and explored solutions. Agree there’s a mismatch between the documentation and reality. Please file a bug (or go a step further and contribute a solution—see below). </div>
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">As far as a simpler solution you were very close in your last idea. Instead, try something like this:</div>
<div class=""><br class="">
</div>
<div class="">
<div id="divtagdefaultwrapper" dir="ltr" class="">
<div class="" style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 12pt;">

<div class="">
<div style="font-family: Georgia; font-size: 15px;" class=""><br class="">
</div>
<div style="font-family: Georgia; font-size: 15px;" class="">You can get a sense of the arguments it’s expecting, by looking, as you started to, into the CAT.configs structure, e.g.</div>
<div style="font-family: Georgia; font-size: 15px;" class=""><br class="">
</div>
<div class="">
<div class=""><font size="3" face="Courier" class="">>> hlp_struct2varargin(EEG.CAT.configs.est_selModelOrder) %serializes a structure into a cell array</font></div>
<div class=""><font size="3" face="Courier" class=""><br class="">
</font></div>
<div class=""><font size="3" face="Courier" class="">ans =</font></div>
<div class=""><font size="3" face="Courier" class=""> 1×22 cell array</font></div>
<div class=""><br class="">
</div>
<div class=""><font size="3" face="Courier" class=""> 'arg_direct' [0] <b class="">'modelingApproach' [1×1 struct]</b> 'morderRange' [1×2 double] 'downdate'</font></div>
<div class=""><br class="">
</div>
<div class=""><font size="3" face="Courier" class=""> [1] 'runPll' [1×1 struct] 'icselector' {1×4 cell} 'winStartIdx' [] 'epochTimeLims'</font></div>
<div class=""><br class="">

<div class="">So you can see that the value for <span style="font-size: medium;" class=""><font face="Courier" class="">modelingApproach</font></span><span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: medium;" class=""> </span>needs

<div>One other source of clues in working with SIFT or BCILAB is to look at the ‘worker’ function behind each
<font face="Courier" class="">pop_*</font> function, in this case<font face="Courier" class=""> est_selModelOrder.m</font></div>
<div>You can decipher the <font face="Courier" class="">arg_define()</font> statement at the beginning to see which arguments it is possible to specify. </div>
<div><br class="">
</div>
<div>It would be great if you took a shot at fixing it, taking as an example the <font face="Courier" class="">
arg()</font> line defining the <font face="Courier" class="">prctWinToSample</font> parameter, then adding your own line to define e.g. a top-level
<font face="Courier" class="">winlen</font> parameter. You’d then need to verify that it will override the
<font face="Courier" class="">winlen</font> already specified in the <font face="Courier" class="">
modelingApproach</font> structure.</div>
<div><br class="">
</div>
<div>Hope that gets you on the way.</div>

then it would run without crashes, however, I feel that I shouldnt have to do that considering it says that it is one of the possible input arguments.
