Hi!
This error (see previous postings) seems to be related to the file size.
I truncated the timeseries to various sizes and managed to execute the
fslstats command for timeseries containing up to 600 volumes. With
longer timeseries the system started swapping and came near to lock-down
while processing (I have 2 GB RAM and 3 GB swap on my laptop) and
finally produced the error. There seems to be drastic change in the
system behaviour when the critical file size is exceeded. The size of
the file I'm trying to process is slightly over 150 MB.
Any suggestions what might be the reason?
Greetings,
Antti
