Problem in processing of data using DPARSF software

Submitted by Bhaswati Roy on Sat, 05/29/2010 - 14:44

 While I was working with the DPARSF software I was facing few problems. I am using the data having three subjects. The data is sorted and anonymised and .dcm files are put in a folder Funraw which is inside Analysis folder.  While processing the data, the conversion of EPI DICOM to NIFTI is been done successfully.
i) While removing first 10 time point, error is occuring. The dialog box is showing "Error in Removing First 10 time point".
ii) If I am skipping the step of removing first 10 time points and moving directly to slice timing step then also I am encountering errors. The dialog box is showing that "Errors were encountered....Error in Slice timing:Sub_001, Error in Slice timing:Sub_002,Error in Slice timing:Sub_003".
iii) If you suggest that data is wrong, then how is it wrong?
iv)Can the problem be related to time point? I might not be giving the current time point. Then please suggests me how to find the time point.
v) If I am doing slice timing solely with the help of SPM5 then there is no problem. No errors are been encountered. Should I proceed by doing slice timing in SPM5, then how to link it with DPARSF?

Dear Bhaswati,
         You need to set the correct number of time points.
         You can do the following to determine how many time points you have:
         1. Convert raw DICOM data to NIfTI images.
         2. Enter in one subject's directory under FunImg which stores the converted image files.
         3. Count how many .img files in that directory.
         Best wishes!

 Respected Sir,
Thank you for your guideline. After putting the correct time point, there was no error for removal of first 10 time points and slice timing was also done successfully. After the completion of realignment, there is a problem in normalization. I am doing normalization by using EPI templates. During normalization, resampling and affine registrations are done successfully but after that error is occuring. This is the error shown:

??? Undefined function or method 'rest_misc' for input arguments of type
'char'.

 Error in ==> DPARSF_rest_sliceviewer at 805
          rest_misc( 'DisplayLastException');

 Error in ==> DPARSF_rest_sliceviewer at 31
             varargout{1}=DPARSF_rest_sliceviewer('ShowImage','');   %by

 Error in ==> DPARSF_run at 562

 Error in ==> DPARSF>pushbuttonRun_Callback at 924

 Error in ==> gui_mainfcn at 96

 Error in ==> DPARSF at 38
gui_mainfcn(gui_State, varargin{:});

 ??? Error while evaluating uicontrol Callback

Please guide me to overcome this problem.Can it be because of EPI.nii? This .nii file is not there and how should I get it?

Hi!
Please install the latest REST first.
Best wishes!

 I have been able to overcome with the previous problem regarding normalisation.For the functional connectivity, the folder formed by the name FC is empty. I have the data in the folder called FunImgNormalizedSmoothedDetrendedFilteredCovremoved. I shall be highly thankful to you, if you can guide me for what might have gone wrong.

Have you defined your ROI and click the checkbox "Functional Connectivity"?
