Dear FSL folks,
I am new to Melodic toolbox and plan to apply it on my resting state data.I use Melodic version 3.10 and I have two questions:
1. On the graphic interface, under the pre-stats toolbar, I have only perfusion subtraction and high pass filter options. However, the lowpass filter is diapppeared!Given that one should bandpass the signal(0.01-0.1HZ) for resting state analysis, I am just wondering why this option has been removed from the graphic interface? Do I also need to turn on the intensity normalization for resting state analysis?
2.There is a recent paper in Neuroimage(http://www.sciencedirect.com/science/article/pii/S1053811911011815) suggesting that the movement would have a substantial influence on resting state results.The authors suggested to use derivatives of a single measure of intensity on each volume as an index to identify severe movement.I am just wondering what is the best way of removing movement from resting state data? I can see in the graphic interface that MCFLIRT is used to realighn the data, but is this really sufficient? Is there any easy way to identify a component(s) which reflects movement and remove it from the data?I will appreciate if someone can refer to any tutorial of doing this?
Many thanks
Kami
