Dear Christian,
I've tried Melodic on the feeds set of data without any problems and the
header looks fine to me.
Yesterday, I've tried it on a 4d set of 9 volumes without any problem. Doing
so on a 30 volumes set gave also no problems, but running it on a 120
volumes set gives almost the same error, but only when the mask was created.
Reading data file filtered_func_data ... done
Create mask ... done
child killed: SIGABRT
I will try to put the data on the web shortly
Pieter
