Hi, REST exparts
Thank you for releasing convenient tool called DPARSF. I have some questions about that.
1. When I have tried to run DPARSF on my Mac. PC, I always met the error said ' time points of your data are 0'. I putted 195 volumes EPI Nifti data of each subjects into one folder and then putted these folders of each subjects into one folder named 'FunImgNormalizedSmoothed'. If I tried to run DPARSF on my Win. PC, same data was recognized as 195 volumes, but I couldn't run because the computer load was out of memory. Is there the way to run DPARSF on Mac. PC?
2. I understand that I have to set covariates on each subjects separately in order to run FC analysis on REST tool. If I run DPARSF, I guess I'll get regressed out hdr. img. data of each subjects. Do this process mean that each data were regressed out by their own covariates? Do this mean each voxel have detrended, filtered and regressed out time course data? If so, is it possible that we can run FC analysis at one time using this regressed out data?
And I have one question about slice viewer of REST tool. Now I preprocess my EPI data with FSL and SPM5 as below.
stripping of non-brain structures
realign(register to first)
slice timing correction
normalize to EPI template (voxel size 2x2x2)
smoothing (FWHM 6x6x6)
Then, I run FC analisis on REST tool and get zFCmap.
But when I see this zFCmap on slice viewer of REST tool, sagittal view was not match to axial view. I mean some part of anterior-inferior region of image (e.g. OFC) exist only in sagittal view but not in axial view. When I see same image with SPM5, this kind of mismatch didn't happen. Why do this kind of mismatch happen?
Thank you in advance for your help. Any suggestion will be really appreciate.
