<div dir="ltr">Thanks Xavier,<div><br></div><div>So I guess the best solution for the first problem is to update yoda; if that's not (easily) possible then maybe you just have to patch the script locally until a yoda 1.6.6 is incorporated into CMSSW.</div><div><br>As for the second issue, I strongly suggest writing a small python script for these sorts of jobs. This allows you to be precise about the format of the inputs, which yoda can only assume. Something along the lines of the python I pasted below below should work for your case if I understand it correctly. Obviously you should double check that the points and errors are really what they ought to be---I can only guess at the meaning of the values in your histogram.</div><div><br></div><div>Chris</div><div><br></div><div><font face="monospace, monospace"><br></font></div><div><div><font face="monospace, monospace">from sys import argv</font></div><div><font face="monospace, monospace">import ROOT</font></div><div><font face="monospace, monospace">import yoda</font></div><div><font face="monospace, monospace"><br></font></div><div><font face="monospace, monospace">f = ROOT.TFile.Open(argv[1])</font></div><div><font face="monospace, monospace">h = f.Get("h2")</font></div><div><font face="monospace, monospace"><br></font></div><div><font face="monospace, monospace">path = "/h2"</font></div><div><font face="monospace, monospace">title = "h2"</font></div><div><font face="monospace, monospace">s = yoda.Scatter2D(path, title)</font></div><div><font face="monospace, monospace">for iBin in range(1, h.GetNbinsX()+1):</font></div><div><font face="monospace, monospace"> y = h.GetBinContent(iBin)</font></div><div><font face="monospace, monospace"> yerr = h.GetBinError(iBin)</font></div><div><font face="monospace, monospace"> x = h.GetBinCenter(iBin)</font></div><div><font face="monospace, monospace"> xerr = h.GetBinWidth(iBin)/2</font></div><div><font face="monospace, monospace"> s.addPoint(x, y, xerr, yerr)</font></div><div><font face="monospace, monospace"><br></font></div><div><font face="monospace, monospace">yoda.write(s, "output.yoda")</font></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Mar 13, 2017 at 7:56 AM, Janssen Xavier <span dir="ltr"><<a href="mailto:xavier.janssen@uantwerpen.be" target="_blank">xavier.janssen@uantwerpen.be</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div> <div>I checked the tarball for YODA 165 and the error is present in there.
