Hi all,
We are trying to run melodic with 4D data. We started with a small group of
10 subjects and melodic ran successfully. Afterwards we increased the number
of subjects step by step up to 147, but kept all the parameters the same.
Although there are no memory or swap problems, melodic does not run
properly. Sometimes the html report says it is still running, while he
quitted doing that. Sometimes he stops running with an error message. For
example:
