I am new to the CCPNMR world and structure calculation using aria.
I am trying to get started by using the "Extend-NMR 4: Structure Calculation with ARIA" Tutorial.
However, when I use the Demofile CcpnDemo006.tgz and doing the steps in "Running ARIA", I get the following errors when running Aria:
...

CcpnDemo006/run1/structures/it0/cns

When looking into one of the generated refine.out files from CNS, I find the following errors:
" -------------------------- Torsion Topology -----------------------------------
Please send a bug report to [log in to unmask]
Please increase the "maximum number of distinct bodies" (torsion_maxtree) and re-run.
%TORSION:TOPOLOGY error encountered: Fatal Topology Error
(CNS is in mode: SET ABORT=NORMal END)
*****************************************************
ABORT mode will terminate program execution.
*****************************************************
Program will stop immediately."
However, I can not find the parameter "torsion_maxtree" in the config file and don't know where I could add it.
I get those errors both when running aria locally as well as on the grid.
The used software versions are Analysis 2.1.5, Aria 2.3
I started by using CNS 1.3, putting the src files from the Aria directory to CNS sources and compiling CNS.
Then I did the same for CNS 1.21 and 1.2. Each gives me the maxtree-error.
All updates in ccpnmr analysis are done.
Any hints in which direction I should search?
Is this a software issue (CNS) or are some of the parameter files incorrect?
Is it correct to apply the files from the aria cns/source directory although the install manual states 'cns_solve_1.1'?
Best regards,
Sebastian Eckert
