Dear Stefan, Yes it was primarily designed for AIMD models, and no there is no such reason that could explain why it fails. > This only happens during the rings analysis other options such as RDF, > angles, and bonds execute without issues. Although probably not too > revealing; below is the error from RINGS: > Well to help you I would need more details (copy of your input, options files and sample of your data), but it seems that you are familiar with compilers I would recommand to build a version of the code using detailed debugging flags. ex for Gfortran: FCFLAGS="O0 -Wall -g3 -pg -ggdb3 -cpp -dA -dD -dH -dp -dP -dy -fvar-tracking -fbounds-check" Then at runtime you will get much more information regarding the error you are experiencing.
