Dear Dr. Yan,

I used the 90*90 FC matrix to calculate the topological metric-Modularity on the GRETNA. Several results can be obtained , but I dont kown their meaning: "community_index_All_Node", "participant_coefficient_All_Node", and "size_of_maximum_component". The author of GRETNA did not explain the meaning of these measurments in the Mannual. Could you help me? 

Thanks very much!

Dear experts and Pro. Yan:

                                                  when I look my results in DPABI Viewer, the colorbar only showed the color in the upper amd lower ends. However,  it did not have any color in the middle of colorbar. I do not know how to set the colorbar manual? Or, anyone know that how to load the colorbar from the mat file. Can you send it to me? my email is:1316289208@qq.com

 Thank you very much!

Resample before CAWS

Dear Dr. Yan,

When I was computing CWAS, I found data should be resample  to voxel size of isotorpic 4mm. But after all preprocessing, all data had changed to 4D which can't be resliced by dpabi's function "Image Reslicer" correcttly.

Or can I set the voxel size to [4 4 4] in Normalize step directly and skip the last resample after all preprocessing? Looking forward to your reply. Thanks in advance!

Hi everyone!

I'm trying to run a single subject rsfmri analysis. I run DPARSF and get my 2 zFC maps , one for each of the 2 sessions (pre and post treatment). The maps look good in the viewer! I put these 2 zFC maps in the stat analysis tool by selecting a paired t test modality, in order to to get a comparison-t-map between the two. Is this right so far? The stat analysis tool look running fine and provide me with a map. However, this map cannot be seen in the viewer. When trying to upload it, matlab provides me with the following error:

 老师您好，我现在做另一组病人的时候一跑到回归分析这一步就自动报错，说没有这个文件，可是我明明是有头动矫正后的文件的，我看了一下报错里面那个文件名称和我自动生成的名称不一样，报错里面提示无法打开rp.mrp_a20160203_132726ep2dboldTR2200GRAPPAs003a001_011.txt，可是我自动生成文件的名称是rp_a20160601_132726ep2dboldTR2200GRAPPAs003a001_011，报错名称里面多了一个mrp，但是我就算把那两个头文件重命名也还是说没有这个文件，我不明白哪里出错了呢？
