Hello everyone,

I am sorry to disturb again, as I encountered another error, and again I can't understand what is wrong. I didn't find anything using google yet.

I have been able to compile CNS 1.2 and now it can be launched correctly from the terminal. On my project this time (not the tutorial of CcpNmr), I have set up an XML file for aria to work. Using the GUI, the project was completed and then I used :

$ aria2 -s test_aria.xml   # test_aria.xml is the name of the xml file that I used

$ aria2 test_aria.xml

Everything started and the structure calculation began. However, a few minutes later, I received some messages saying that the whole 20 structure calculation failed, and that I should check CNS output for errors. (I joined a screenshot in png format for you to see the output).

The thing is, the path to CNS output is empty. There are no cns files there. And I didn't find any files of use yet. Has anyone encountered a similar error?

There are multiple options that I can already consider :

1. I'm using google-drive ocamlfuse to work with my cloud, and maybe it is a problem for whatever reason. I can allocate more space to my ubuntu partition and do copy all the files to a local space. But i'm skeptical about that, it shouldn't be a problem.

2. CNS compiled without visible errors, but is not functional yet. I really don't know how to do better than I already did with my last question.

3. I could stop using local Aria and try AriaWeb but as I am new to NMR structure calculation, I do not know how to set up the parameters correctly. The jobs I tried to launch did not produce anything decent yet. My NMR supervisor also tried with one of her older projects that resulted with a publishable structure on Aria2 locally, but with AriaWeb she didn't get a good result either with the default parameters.

I have been struggling with these NMR structure calculations for over a month now, and starting to lose faith. Please help me, I don't really want to deal with bad x-ray diffraction nightmares again!

Thanks again,
