rs-fMRI Preprocessing

Submitted by longhongquan on

Hi Prof Yan,

I am an undergraduate student in Singapore. I have asked you some questions before and  I would like to express sincere thanks for your helpful replies.

At current stage, I am trying to perform the following data processing on HCP data for functional connectivity analysis. I tried several tools (FreeSurfer, SPM, REST, DAPBI) and did not find an intuitive one. Now I tried RESTplus, which seems to be the latest updated one, and consider it to be suitable for my work.

Problem with conversion of EPI/T1 DICOM to NIFTI

Submitted by David on
Hi,
 
when I'm trying to convert EPI and T1 DICOMS to nifti, DPABI gets stuck in between. That is, it converts some data but then it just runs and runs without error message but not data is being converted anymore. For example I have raw dcm data from 30 test subjects I want to convert. DPABI starts and converts lets say 27 of the subjects EPI data, but it then goes on and on without converting more data and the T1 data conversion does not even start. I tried it with an older version of DPABI as well as with the latest version (V2.0_151201).

Question about CWAS

Submitted by YukiSakai on

Dear DPARSF experts,

 Thank you for developping this useful tool!

 I have question about CWAS.

 Although it woks very well in most cases, I got strange results sometimes. I attached the example of F_1_CWAS.nii (example.png). Like this, in some cases, I got nothing. I checked the all preprocessing steps, but there were notihg wrong. Of course, there were no apparent erros in all steps. Why did it happen?

 Best,

 Yuki

What are those predefined spheres?

Submitted by phil1022 on

Dear Chao-Gan,

    In your most recent version of DPARSFA, you added a new version of templete. In this new templete, once clicked in the Define ROI interface, there are a lot of predefined 5 mm sphere ROIs along with AAL and other ROIs.

    I did not pay attention to them at begining which turned out to be over 70 G of masks when I selected "wrap back to native space".

Use DPABI/DPARSF for task-based fMRI analysis without T1 images

Submitted by lindazhang on

Hi Dr Yan,

Thanks for releasing the useful DPABI/DPARSF. But the problem I am encountered now is: my data doesn't include T1 images, so cannot conduct Segement by DPABI/DPARSF. Then furtherly, I cannot use the motion correction steps which is very important when constructing the functional network. So do you have any advice for handling this situation? Or there is something I have not figure out of using this toolbox?

Thanks a lot.

Best,

Linda

How is the relations between ALFF, ReHo and fALFF?

Submitted by daiqingshi on

Dear Dr. Yan,
Have any studies examined the relations betweeen ALFF, ReHo and fALFF?
In my studies, the ReHo of LIFG were negatively associated with task effect of inferior LIFG, while the ALFF of LIFG was positively associated with task effect of superior LIFG. So I am interesting in the relations among these three indices.
thanks.

Undefined function 'y_Write' for input argument 'nifti'

Submitted by Dina Dajani on

I am getting an error when I try to run preprocessing with DPARSF_V3.1 (error is attached) but basically it says there is an undefined function 'y_write' for the input argument 'nifti'

 

I also attached my pipeline.

 

Thank you for any assistance,
