Hi Victor,
<div><br>
</div>
<div>I think you would be better initially trying to get this working from the command line before trying to use the GUI. It will be much easier to find the error. </div>
<div><br>
</div>
<div>Looking at your screen grabs, I cannot see any errors (other that the line saying “RETURNED ERRORS”). It looks to me like vex2difx did run OK and see now errors from difxcalc.</div>
<div><br>
</div>
<div>Regards</div>
<div>Chris</div>

<div style="margin-top: 0px; margin-bottom: 0px;">So I am using trying to run "Experiments" from the GUI, as shown in the image below:</div>

<br>
<b>Case 1:</b><span class="Apple-converted-space"> </span>I use the<span class="Apple-converted-space"> </span><span>repository</span>'s 'test-lsb.vex' and it generates a .v2d file in the tab "Final .v2d File". And when I click "Apply" in the New Experiment

<div style="margin-top: 0px; margin-bottom: 0px;"><b>Case 2:</b><span class="Apple-converted-space"> </span>I use the<span class="Apple-converted-space"> </span><span>repository</span>'s 'test-lsb.vex' and the<span class="Apple-converted-space"> </span><span>repository</span>'s

<br>
<span id="cid:383affae-fc54-4cfe-8d33-a2d560aefa79"><provided_v2d_error.png></span><br>
<br>
So in case 2, the error message shows vex2difx RETURN ERRORS, but it generated the needed files anyway, and the .im file is created, but somehow the GUI is showing it is still waiting for it.<br>

<div style="margin-top: 0px; margin-bottom: 0px;">Hi all,</div>
<div style="margin-top: 0px; margin-bottom: 0px;"><br>
</div>
<div style="margin-top: 0px; margin-bottom: 0px;">My name is Victor, a software engineer at<span class="Apple-converted-space"> </span><span>National Astronomical Research Institute of Thailand (NARIT)</span>. I am new to VLBI and DiFx. I have created a 2-node
DiFx cluster (v.2.8.1). I am able to use the provided synthetic test "test-lsb.vex" and the DiFx commands to get the final .fits file.</div>
<div style="margin-top: 0px; margin-bottom: 0px;"><br>
</div>
<div style="margin-top: 0px; margin-bottom: 0px;">I am also able to run the guiServer, gui client, calcServer, mk5daemon (without actually having the mk5 hardware). On the gui client, I have the processor node shows up in the hardware monitor. Now I am trying
to run "Experiments" from the GUI with the same synthetic test-lsb.vex file and generated vdif data. But when I execute the experiment, I ran into error on when running "calcif2" or "difxcalc" so the experiment stuck on waiting for the ".im" file. Also I am
not sure where I can input the generated vdif data during the experiment. Appreciate any pointer or guidance. My goal is to see how an Experiment is run from start to finish. Thank you.</div>
