I think the LKB's EDS code will more aggressively search for a top for the EDS graph during conversion, perhaps looking to the INDEX. If anyone (Stephan?) cares to explain the procedure for selecting tops in less-than-perfect MRSs, I'd be happy to try and implement it in PyDelphin. Otherwise I'll just try to make the error message more informative.</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif"><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Sep 10, 2020 at 2:44 AM Alexandre Rademaker <<a href="mailto:arademaker@gmail.com">arademaker@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><br> Hi,<br> <br> Are the following two MRSs considered valid?
