图像处理中的困惑

老师们好,我在处理一批图像,但是这些图像采集的不太好,主要是结构像、功能像图像信号不均匀,额叶整体信号很低,甚至肉眼难以分辨灰白质(听说当时MR机器出了点问题)。静息态图像配准标准化效果不好,但是做VBM分析分割、标准化的图像看起来还不错。另外部分图像相位编码方向可能是左右。

用dpabi处理被试灰质时,进行到roi signal出现了报错

尊敬的严老师:

         您好!我在用dpabi处理被试灰质时,进行到roi signal出现了报错,我尝试了好多操作也问了周围的同学,但是还是不行,麻烦老师帮忙看看我的设置是不是出现了问题,谢谢老师啦!

相关的设置信息和报错信息如图片所示,其中在sphere中坐标设置是选取了之前操作中跑出来的cluster中peak的坐标值(就是选的数值比较大的坐标值)

非常感谢老师在百忙之中的解答。

 

祝好!

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?
