Creating mask of significant difference ROIs from ttest

Submitted by FaezeVedaei on Thu, 02/18/2021 - 22:49

Hi

 

I did two-sample ttest using statistics tool and got the list of clusters after multiple comparison correction (FDR correction). I just could not find the way to create specific masks for the regions survived multiple comparison correction. Can you please guide me how I can do this?

Thank you

Error using DPARSFA_run (line 819) Index exceeds the number of array elements (0).

Hi there, 

Thie above error seems to appear after the slice timing was completed successfully. I've checked that

1. all the subject folders have .nii file in the FunImgA directory

2. all of these .nii files have the same time point

3. all the subject folders have a .nii file in the T1Img directory

it would seem that the next step is the field map correction

i have the following field map files within the FieldMap directory for all subjects:

FieldMap/Magnitude1Raw/002/Mag1.nii

FieldMap/Magnitude2Raw/002/Mag2.nii

Statistics information after multiple comparison correction

Submitted by FaezeVedaei on Fri, 02/12/2021 - 18:20

Hi 

I just wanted to ask if there is a way to get detail information about significant clusters, name of the regions in each cluster, the coordinatin, p-value, t-stat and other information after applying multiple comparison correction in DPABI, viewer?

I already did some statistical tetsts including two-sample and one-sample ttest. But need to get information from the result. I really appreciate it if you guide me to do that.

 

Thanks

严老师：

您好，我这两天在做静息态预处理时，Normalize无论选择by using EPI templates 还是by DARTEL时，都会报错，不知道是什么原因，希望老师能够帮我找找原因。设置参数和错误代码如图所示，使用的是DPABI_5.1 和SPM12b。
