It requires a mask with size 61*73*61, and I used the default mask (BrainMask_05_61x73x61.img), but it still goes wrong. Why did this happen?
Hi all,
I’m encountering a problem with the FieldMap Correction in DPARSF pointing to
DPARSFA_run (line 812): „Index exceeds matrix dimensions.“
I have 2 phase dicoms and 2 magnitude dicoms per slice and as far as I can tell the nii look ok and are saved in the correct folder.
The settings I have used are
Cfg.FieldMap.IsNeedConvertDCM2IMG: 1
Cfg.FieldMap.IsCalculateVDM: 1
Cfg.FieldMap.EPIBasedFieldMap: 0
Cfg.FieldMap.IsFieldMapCorrectionUnwarpRealign: 1
Cfg.FieldMap.TE1: 0
Cfg.FieldMap.TE2: 0
严老师您好，我有如下三个问题：
问题一：在使用dpabi的时候，我们可以获取到功能连接矩阵，是不是文件夹Results \ ROISignals_FunImgARCWF \ ROICorrelation_sub_xx.mat吗？
问题二：功能连接矩阵为116x116，我看了下矩阵中所有的数都是不为0的，是对脑区进行全连接吗？可能会存在有为0的数吗？
Dear colleagues,
I hope you are fine. I am doing a test of rs-MRI analysis of one subject using DPABI and aftr the step of reorientation I got this message
尊敬的严教授，您团队啥时候DTI的处理模块呢
各位老师，请问TR一致，Time points不一致的影像数据可以比较吗？比如Alff，Reho，DC，用他们的Z值图可以直接contrast吗？
Hello,
Dear all,
In the statistical analysis, we need to choose a binary mask.
What kind of binary masks I can apply? If I turn to the group-wise GM mask, it seems there're too many comparisons, leading to failure in the tfce+fwe correction (p<0.05).
Can I use the |Z|>2 of the Z map as the binary mask instead to reduce the number of comparisons?
Thanks!
