REST and DPARSF error on demonstration data set

Submitted by Jian Chen on Mon, 07/28/2014 - 08:32

I am using linux-Mint (ubuntu) system with MATLAB R2013b and SPM8. I could not get REST work at first place: it could not find subjects in the  ProcessingDemoData directory.

Anyway I have got DPARSF almost work except FC part. I have attached my DPARSF setup file here.

For the FC part I have the following errors:

     Calculating Functional Connectivity by Seed based Correlation Anlyasis...
     Read 3D EPI functional images: "/home/jiancscratch/tryREST/ProcessingDemoData/FunImgNormalizedSmoothedDetrendedFilteredCovremoved/Sub_001".

     Load mask "Default".Error using  -

Error in DPARSF (line 48)

It will be very much appreciated if you can give helps.

Hi,
the error message is ''Matrix dimensions must agree'' , that means the dimension of your mask you specified does not agree with the dimension of your functional data (sub001).
You can reslice the mask (REST-Utilizes-Reslice Image) to the resolution of your functional data (e.g., 3x3x3 mm).

Hi Jian,
Please check the dimension of your demo data. I guess the dimensions of your demo data and the defulat mask are not equal.
You can find the defualt mask (Voxel size:3x3x3, dimension:[61,73,71]) in DPARSF or REST toolbox (in the 'Mask' file).

Best regards,
Binke
