Discussion group for the ARIA software

Hi JC,

did you do the aria setup first?
I think you have run
aria2 -s file.xml
before you do 
aria2 file.xml

On the GUI issue - on a Mac I have found it helpful to follow these 
instructions:
http://aria.pasteur.fr/faq-1/no-tix-on-mac-use-ccpnmr-analysis-as-a-python-tcl-tk-tix-surrogate
 
But you may find the same works on Linux. It basically enables you to run 
Aria with the CCPN python which has all the packages installed that Aria 
needs for the GUI. This should work equally well with CcpNmr 2.4 or 2.5.

All the best,

Vicky

    Good morning/afternoon everyone,

    I am a PhD student and I am currently trying to locally calculate some NMR
    structures with Aria, on a Ubuntu 20.04 LTS plateform.
    To be honest, I've been trying for a week now and I finally installed
    "correctly" all the softwares (Aria2.3, CNS1.2) and I am using CcpNmr 
2.5.0.

    I'm doing the tutorial dedicated to structure calculation of CcpNmr.
    However, now that the project is finally set up, I get an error when i'm
    starting the calculation with Aria.
    Using this command: $ aria2 /path/to/my/project/project.xml, I get a 
strange
    error that I cannot understand.

    "IOError: USER ERROR <aria.cns.CNS> File 
"/some/path/to/aria2.3.2_05.08.2019/
    aria2.3/src/py/aria/cns.py", line 2038 in prepare
    An error occurered during creation of the PSF-file: 
"/some/path/to/Tutorials/
    CcpnCourse3a/run1/cns/begin/CcpnCourse3a.psf" could not be found."

    Also, I cannot use the GUI interface with Aria because I get a strange 
error
    about Tix package being not installed and I didn't find any solution to 
it.

    Does someone have a solution to this problem ?
    Thanks a lot for your time.

    JC
