Problem with GUI and X11 Authorisation
Greetings,
I'm new to Multiwfn (and somewhat new to Linux and CentOS 7) and I can't get the GUI for Multiwfn to work. Below are some details of my problem.
I access a ia86_64 CentOS 7 Linux server remotely using MobaXterm. I have no problems getting XWindow applications like Gaussview 6, openbabel GUI, VMD to show the GUI on my Windows 10 laptop using MobaXterm. When I run Multiwfn, I get the following message:
Multiwfn -- A Multifunctional Wavefunction Analyzer (for Linux 64bit)
Version 3.5, release date: 2018-Apr-6
Project leader: Tian Lu (Beijing Kein Research Center for Natural Sciences)
Below paper *MUST BE CITED* if Multiwfn is utilized in your work:

Input file path, for example E:\Najica\Najica_Hiiragi.wfn
(Supported: .wfn/.wfx/.fch/.molden/.31/.chg/.pdb/.xyz/.mol/.cub/.grd, etc.)
Hint: Press ENTER button directly can select file in a GUI window. To reload the file last time used, simply input the letter "o". Input such as ?miku.fch can open the miku.fch in the same folder as the file last time used.
If I press "ENTER" at this point, I get the following message:
MobaXterm X11 proxy: Unsupported authorisation protocol
>>>> Can't open X Window display! ( )
Any suggestions as to how I can get the GUI to work remotely with MobaXterm?
Thanks,

Re: Problem with GUI and X11 Authorisation
Dear Clayton,
Since I have never used MobaXterm, I can hardly say how to solve it. If you really need to perform some time-consuming calculations on remote high performance server, you can consider to use the "noGUI" version of Multiwfn instead. If the cost is not quite high and thus can be easily afforded using local computer, I suggest simply using local computer to run Multiwfn.
Best,
Tian

Re: Problem with GUI and X11 Authorisation
Dear Tian,
Thanks. I'm wanting to use the RESP charge calculation feature which seems to be most well-developed in the current development version. Is there a "no-GUI" of that for Linux-64 systems? I'd like to be able to use Guassian16 (and cubegen facility) on my Linux server system. Maybe there is a way to just use commands without having Multiwfn try to enter the GUI mode?
I have installed Multiwfn on my Windows10 laptop to be able to use the full-featured graphics capabilities (which seem very useful). But I only have Gaussian on the Linux system. The Linux system is local but is rack-mounted in our server room and does not have a monitor/keyboard/etc.. That is why I access it remotely using a terminal emulator.
Thanks for your help.
