Dear members of the R-fMRI Network,

As a current member of OHBM, you are cordially invited to participate in the council election of the Organization for Human Brain Mapping (OHBM). The elected nominees will represent you to work on the OHBM Council and Program Committee.

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,

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)?
