Hi experts,

I have a question about AlphaSim correction and how to correclty apply a threshold. I'm pretty new to the field, so my question might be very simple for you.

Basically I'd like to apply a threshold o voxel p 0.005, cluster p 0.05 to my T map.

Once I've loaded my T image on the viewer, I've opened alpha sim option and selected a mask and voxel p value (0.005), I run alpha sim and I get my txt output. At this point I look for alpha 0.05 and use the cluster size indicated in the same line as minimum cluster size using the option 'set cluster size'.

Hi,

Is there a way to turn off the warning message, that gives notification when no co-images (the cropped and reoriented from the dcm2nii) were found? That would be very helpful, because I have to preprocess a lot of datasets and did not reorient my strucutural images and it is cumbersome when the preprocessing stops because of the warning message and I have to manually press yes to continue. When I run some preprocessing over night it is especially inconvenient when the preprocessing does not go on automatically :(. 

Hi. Dr. Chao-Gan Yan

I am Seungnam 

I am analyzing the rFMRI data using DPARSFA progrm. Thank you for good program.

I am using the subfunction of Functioanl connectivity and Degree Centrality of DPARSFA.

I understand that Degree Centrality means functional connectivity strength, that is global functional connectivity density. Am I right?

How do you calculate the Degree Centrality?

Could I know the equation of Degree Centrality and it's reference?

I already had a Buckner et al. 2009 and Zuo et al. 2012. But still not clear the concept.

Hi,everyone

After data preprocessing,I have gotten the 'ROISignal_*.txt' using own defined ROI.

But I wanna  get a graph about time and BOLD, time acts as x-axis,BOLD acts as y-axis.

Like this(img in the right):

Could you pealse tell me the detail steps ?

Waiting for your reply.

Sincerely,

LJH

      现在部分文献中计算FCD的时候提到了 分别计算 long-range 和 short range 的 FCD，不知道DPARSF工具箱经过怎样的设置以后可以具备这样计算的功能？多谢指教！

Dear Prof. Yan,

Hi! When the mp2Rage T1 images is used as structural images, the full pipline can be done. However, the  "No co*T1 image is found"(Please check the attachment) shows at the early stage of preprocessing. How could I solve the problem?

Thanks a lot!

Best wishes,
