<div class="">Dear Graeme,</div>
<div class=""><br class="">
</div>
<div class="">thanks for your quick reply. Yes exactly, four 1-D histograms with varying x and y path fields is what I’m after. I suppose I can work around that for this analysis, but as ATLAS Rivet contact I can already see this seemingly minor feature cause
an awful lot of frustration elsewhere.</div>
<div class=""><br class="">
</div>
<div class="">There are already many Rivet analyses relying on path names containing not just the "x01" that would need changing and I’m not sure this is a path we wanna head down to be honest. On the experiment side, we have elaborate MC validation frameworks
that make use of Rivet analyses and their existing path names, so I’m worried that changes to the now well-established naming scheme will cause havoc all over the place…</div>
<div class=""><br class="">
</div>
<div class="">In fact, what will happen when (not if) we sync the Rivet reference data repository against HEPData? I’m fairly sure this will break everything and we’ll receive lots of abuse...</div>
<div class=""><br class="">
</div>
<div class="">I’m cc’ing the Rivet list as I think the Rivet developers (and users) need to be aware of this and this needs to be discussed. I wonder whether a comprise is feasible where we just add an additional 'qualifier' field to the YAML input, that would
allow us to set the d01-x01-y01 style YODA names?</div>
<div class=""><br class="">

<div class="">Cheers,</div>

Good question. On the old HepData site, a data table could be defined as "*data: x : x : y : y" (in the oldhepdata format, corresponding to two independent variables and two dependent variables), giving the YODA path names you mention, i.e. four 1-D histograms:
y1(x1), y2(x1), y1(x2), y2(x2), written as Scatter2D objects. But an alternative interpretation of such a table might be two 2-D histograms, y1(x1,x2) and y2(x1,x2). To remove the ambiguity, we use only the latter interpretation on the new HEPData site,
writing two Scatter3D objects with path names d01-x01-y01 and d01-x01-y02.<br class="">
<br class="">
Since I think you want four 1-D histograms rather than two 2-D histograms, you need to define two different tables, each with one independent variable and two dependent variables, giving YODA path names:<br class="">
d01-x01-y01<br class="">
d01-x01-y02<br class="">
d02-x01-y01<br class="">
d02-x01-y02<br class="">
So the new HEPData site will always define YODA path names with "x01" and it is not possible to get the path names mentioned in your email. I hope this is not a problem for you, but you might need to modify the path names in an existing Rivet analysis.<br class="">
<br class="">
Best regards,<br class="">

Hi,
<div class=""><br class="">
</div>
<div class="">I’m trying to work out how to write a YAML input file that will be interpreted as table with 2 different independent variables, each with two dependent variables. In YODA language the idea would be something like:</div>

<div class="">d01-x01-y01</div>
<div class="">d01-x01-y02</div>
