<div dir="ltr"><div><div><div><div>Hi Dan,<br><br></div>Since you are iterating over single epochs, it might make more sense to use the iterator which returns an evoked object. You can do something like:<br><br></div>for ev in epochs.iter_evoked()<br> ev.crop(tmin, tmax)<br><br></div><div>Does this help? Fix to the docs is more than welcome.<br><br></div>Best regards,<br></div>Mainak<br><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Apr 5, 2016 at 10:05 PM, Dan McCloy <span dir="ltr"><<a href="mailto:drmccloy@uw.edu" target="_blank">drmccloy@uw.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><span>On Tue, Apr 5, 2016 at 12:19 PM, Chris Holdgraf <span dir="ltr"><<a href="mailto:choldgraf@berkeley.edu" target="_blank">choldgraf@berkeley.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">sometimes it's more useful to return arrays.</div></blockquote><div><br></div></span>Sure, but that's why there is a get_data method, right? IMO the
docstring reflects how I expected it to work before even reading the
docstring, so my vote would be to make .next() actually do that, rather
than changing the docstring to reflect what it does currently. Issue
