I can't find my password back of the forum "http://rfmri.org/", and I can't creat a new account, so I post my question to the maillist directly.

Hi,
i have a question regarding the preprocessing of my resting state data for a subsequent investigation based on the graph theory. The common preprocessing procedure for a subsequently graph theory based estimation include the following steps:
* despike
* slice timing correction
* 3D motion correction
* Regression with motion parameters
* Register to MNI
Regarding Aurich et al. (2015) the following steps are also recommended to use:

Hi,
I am new to DPARSFA. AutoMask doesn't seem to be working for me. It runs without errors, but doesn't properly mask it brain. It just generates a white rectangle that covers the entire area. Screenshot is attached. Please advise. Thanks.

Dear experts,
I computed ReOh maps for some patients and controls in DPARSFA (running the participants all together, hence with the same processing settings) and got maps where the values are not between [0 1], is this correct? I expect having values between 0 and 1 due to the computation of KCC. I obtain values between 0 and 1.6/1.8.
Please advice if correct,
Thank you,
Kind regards,
Bianca De Blasi

Dear experts,
I am wondering whether you can give me more information about ReOh and ALFF maps or suggest some references where I can get the following information:
1) What are the typical ranges and inter subject variability of ALFF and ReOH maps?
2) Do I need to intensity normalise the maps output from DPARSFA for the ALFF and ReOh or can I use the m* output directly in the statistical analysis? If intensity normalisation is needed, could you suggest by what intensity value (whole brain, gm value)?
