Hi,
in the previous email I sent you the link to the data. After that I have
actually tried to do the analysis again - this time with 12 (instead of
11) volumes. The datset that i sent you is created by averaging
timepoints in the original dataset. There are 12 points used to sample
the rf, but I excluded the first one because that one was sampled only
once. That's how I ended with 11 volumes. But the analysis with 12
volumes works fine - no crashes. If you want I can send you this data
too.
Thanks!
