<p>Hi, this seems like quite a niche problem that you are facing, perhaps a bug in the GUI of some kind. Although it's on-topic, I think you're unlikely to find somewhere here who can help (unless the popart devs lurk here). I would suggest emailing the authors, but they point towards the github which mostly seems to be ignored.</p>

<p>I am trying to create haplotype networks in <a href="http://popart.otago.ac.nz/index.shtml" rel="nofollow noreferrer">PopART</a> (Population genetics with Reticulated Trees*) which I have successfully done many times in the past.</p>
<p>Two weeks ago the program was working fine for me but recently I am unable to load files. What happens is that when I go to load a nexus file through the &quot;nex&quot; button, or through the &quot;file/import/alignment&quot; or &quot;file/open&quot; options nothing loads.</p>
<p>There is no error message, instead nothing happens. This occurs with both files I have recently created and with files that I have successfully loaded in the past. I've sent files to other people and everyone has been able to load the files using PopART on their computers. I am running macOS 10.15.6 and have tried turning my computer off and on as well as uninstalling and reinstalling PopART. I also thought that maybe Java wasn't up to date on my computer but I don't think PopArt runs with Java. Any help would be very appreciated!</p>

Can't load files into PopART
# Can't load files into PopART

(Asked by: username_0 on 2021-06-16)

I am trying to create haplotype networks in [PopART](http://popart.otago.ac.nz/index.shtml) (Population genetics with Reticulated Trees\*) which I have successfully done many times in the past.

Two weeks ago the program was working fine for me but recently I am unable to load files. What happens is that when I go to load a nexus file through the "nex" button, or through the "file/import/alignment" or "file/open" options nothing loads.

There is no error message, instead nothing happens. This occurs with both files I have recently created and with files that I have successfully loaded in the past. I've sent files to other people and everyone has been able to load the files using PopART on their computers. I am running macOS 10.15.6 and have tried turning my computer off and on as well as uninstalling and reinstalling PopART. I also thought that maybe Java wasn't up to date on my computer but I don't think PopArt runs with Java. Any help would be very appreciated!
