Dear all, I am a first time user of FSL and I tried to run melodic ica. I've installed FSL on a FreeBSD host machine without any problems. Then I created a 4d file containing 160 volume images with avwmerge. When I run Melodic ica, the report.log file shows /opt/fsl/bin/avwroi /data/fmri/patient/4dtest example_func 80 1 /opt/fsl/bin/ip /data/fmri/pat/van_thuyne_frank/moto/4dtest filtered_func_data 10 -s 1.27388535032 -t 16.6666666667 -1 THRESHOLD 60.602500 rm -rf prefiltered_func_data* /opt/fsl/bin/melodic -i filtered_func_data -o /data/fmri/pat/van_thuyne_frank/moto/4dtest.ica -v --nobet --bgthreshold=10 --tr=3.0 -d 0 --mmthresh="0.5" --report --Ostats Melodic Version 2.0 beta Melodic results will be in /data/fmri/pat/van_thuyne_frank/moto/4dtest.ica Reading data file filtered_func_data ... child killed: SIGABRT Can you help me out?
