How to caculate how many volumns were scrubbed for each subject using DPARSFA?

Submitted by Yangmei Luo on
Hi DPARSFers,
 
I used the "scrubbing"  module in DPARSF  to clean my data. Is there any method to caculate how many volumns were scrubbed for each participant? The DPARSF seems not to report this data. 
 
Thank you in advance for your kind help. Any help is appreciated.

Hi Yangmei,

You can find "Number of FD_Power>0.2" in HeadMotion.tsv under RealignParameter.

If you use other criterion to scrub the time series, you can use the file FD_Power_SubXXX.txt or FD_Jenkinson_SubXXX.txt under RealignParameter/SubXXX to count the number of time points scrubbed.

Hi Chao-Gan,

Thank you for your quick response. I used the criterion " FD_Jenkinson > 0.5". So,  I need to caculate the number for each subject one by one, although it is a little bit time-comsuming. 

I am greatly appreciated your kind help. 

Best,

Hi Yangmei,

Make a stop point on the beginning (e.g., Line 40) of DPARSFA_run.m

They run DPARSFA, and run the following scripts when matlab stop at debugging:

for i=1:AutoDataProcessParameter.SubjectNum

    cd([AutoDataProcessParameter.DataProcessDir,filesep,'RealignParameter',filesep,AutoDataProcessParameter.SubjectID{i}]);
    FD_Jenkinson=load(['FD_Jenkinson_',AutoDataProcessParameter.SubjectID{i},'.txt']);
    NumberFD_Jenkinson_05(i,1) = length(find(FD_Jenkinson>0.5));
end
 
Best,
Chao-Gan
