Slice timing error: Improper assignment with rectangular empty matrix.

Submitted by nertman on Wed, 08/27/2014 - 03:02

I am trying to use DPARSFA to preprocess some .nii.gz files. I think for some reason the program is not detecting the time points correctly. If I leave the files as .nii.gz, the slice timing module will begin, and then give me this error (please continue reading after pasted content):

DynamicBC 中每个时间窗内设置多少个时间点可以被接受？

Submitted by cheungmen on Wed, 09/03/2014 - 09:15

 各位老师，
       您们好！
       关于运用动态方法研究静息态功能磁共振数据，我想知道动态方法中的每个时间窗内至少需多少个时间点才算合理？有什么依据吗？
       还有，计算局部一致性，也至少需要多少个时间点才可以被接受？
       恳请各位老师帮忙解答，谢谢！

Paired t-test in dpabi with demo data

Submitted by pritha on Wed, 09/03/2014 - 10:02

Hi there,
When I do 1 sample or 2 sample t-tests in dpabi with demo data it works fine but when I try paired t-test it produces following error:
Error using  .*
Array dimensions must match for binary array op.

Error in y_GroupAnalysis_Image (line 58)
MaskData = any(DependentVolume,4) .* MaskData; % skip the voxels with all
zeros
