DICOM数据转化

严老师好:

我拿到的DICOM数据是每一个slice(比如有35个)上每一个TP(比如有240个)一个DICOM文件,一共8400个DICOM文件。老师展示的DeMo数据中的FunRaw中,是一个TP一个文件(共240个文件),请问应该如何将前面的8400个文件转化为后面的240个文件呢?

谢谢

关于用统计分析模块添加协变量的疑问

尊敬的严博士,我在用统计模块进行两个独立样本T检验时,在添加患者组和对照组后,还添加了Mean FD,性别,年龄,教育年限等协变量,但是我发现在点Run之后,并没有运行协变量,得到结果和我没有添加协变量时是一样的,我怀疑是我编辑的协变量文件不正确。例如我建立一个记事本文件(OCD.txt),假如我有13个被试,我就编辑成13行,4列;每一行从左到右以此是:性别,年龄,教育年限,Mean FD;打开后内容如下:

1 24 16 0.061
1 55 12 0.089
1 18 09 0.107
0 44 15 0.057
0 36 09 0.093
1 38 16 0.109
0 33 11 0.116
0 23 16 0.062
0 29 12 0.054
1 17 11 0.117
1 49 09 0.104
0 27 15 0.127
1 35 12 0.048
(想让老师们帮我看一下,我这个编辑的方式是不是有问题?感谢老师,我爱你们)

关于用统计分析模块分析VMHC结果的疑问

结果如下:DLH 0.091699 voxels^-3 before correcting for temporal DOF

 

FWHMx = 3.744741 voxels

FWHMy = 3.687451 voxels

FWHMz = 3.645997 voxels

FWHMx = 11.234224 mm

FWHMy = 11.062353 mm

FWHMz = 10.937990 mm

DLH = 0.092841

VOLUME = 174972

RESELS = 50.345928

尊敬的严博士,关于这些结果我不是很明白,我想了解一下上面这些结果分别表示什么意思?感谢亲爱的严博士

为什么我的mask图像是方形,完全不是头颅的形状

为什么我的面具图像是方形,完全不是头颅的形状
我检查过,在我进行质量控制模块时,我的T1Img,FunImg,以及标准化后图像都是正常的,但是我的面具文件里的图像都特别奇怪,完全不是形似头颅,而是方块形的的,求老师们给我一些建议,可能是哪里出问题了,还有就是我不知道这个论坛,怎么发图片信息?

How to add covariates in Mixed Effect Analysis?

Dear Dr. Yan,

I encountered a problem while doing Mixed Effect Analysis. I wanted to add covariates (age, gender and handness). But the problem is that the covariates are the same for both condition 1 and condition 2.

I added as

group1_cov.txt

group1_cov.txt

group2_cov.txt

group2_cov.txt

Then Dpabi ran for hours and gave weired results. I also tried to name the covariates differently but it didn't work either. I wonder what is the proper way to add covariates in Mixed Effect Analysis. 

Thank you!

Best Regards,
