FieldMap Correction

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

获取脑区功能连接矩阵问题

       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?

请问这些图和表的作图软件和提值方式。

各位前辈好,

(1)请问如何求出图1中,各个部位的mean FA值;现在会的是用matlab提取各个被试的总的FA值

(2)请问图2中,这些比较美观的图是用什么软件做的?

 

谢谢指导,入门小白不胜感激。

祝好!

TR一致,Time points不一致的数据可以比较吗?

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?
