DPARSF--the detected time points of subject "..." is: 0, ... slice timing correction

Submitted by dominic on Thu, 10/29/2009 - 12:34

 Dear DPARSF developers, 

I'm trying to use the DPARSF toolbox to process some nifti (hdr, img) resting state sequences. It seems to be able to read the files (stored in FunImg), but when I un-tick the 'Slice Timing' box it appears with the message "the detected time points of subject "..." is: 0 ...". Does this mean that we have to conduct the slice timing step? 

many thanks,

Dominic

opening DPARFS in mtlab

Submitted by brodhinooch on Thu, 10/29/2009 - 21:33

hello

i have downloaded the DPARFS toolkit and I cannot open it in MATLAB. Could someone please instruct me on what to type in the MATLAB window to get this toolkit to open. For example, to open the resting state toolkit I type: rest.

thank you in advance for help regarding this matter.

cp: preserving permissions for "...": operation not supported.

Submitted by dominic on Fri, 10/30/2009 - 07:59
Hi DPARSF developers, 

Thanks very much for your help so far. There is another error that I'm having difficulty understanding--printed below. I'm running DPARSF from spm5 using MATLAB 7.4.0. This error occurred after running the normalisation steps. In particular, I don't know why copying permissions and the ACL is not supported only for the files mentioned. 

Once this problem is fixed should I run DPARSF from the normalisation step again? 

Many thanks in advance for your help.

Q&A: Convert r to p

Submitted by YAN Chao-Gan on Wed, 11/04/2009 - 10:47

Dear Chao
I have a question regarding you program y_corr2p, that was very useful to me. I would like to know how the P value is calculated. All other algorithms I have been using use the mean(r) and std(r) across all subjects, but your code is independent of the number of subjects, only taking into account the number of time points in the series. I am curious about how it is calculated
best regards
Pablo
