DPABI/DPABISurf/DPARSF

Hi,

just found out, that when using Dartel the Group mask as created with the GroupMask tool with DPABI shows holes, i.e. missing/empty voxels.  The indivual wAutoMask-files for the subjects also have those holes. 

Solution seems to be to smooth the wAutoMask files, which gets rid of the holes  and the GroupMask looks fine thereafter. 

Just something that can be considered in next releases :)

greetings

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！
