Wrong ROI definition when extracting CSF/WM signal etc

Hello, I am receiving a bug when extracting the ROI signals (i.e white matter, CSF) for the nuisance covariates regression. The error appears after slice timing, realignment have been done. The error I received is below, I believe it is due to DPARSFA not being able to find the masks in the working directory. The error only appears with DPARSFA. My data was converted from DICOM --> NIFTI outside of DPARSF, then converted into spm format using freesurfers mri_convert to 208 indiviudal img files. The original raw data are as follows: Voxels: 128 x 128 x 29 Dimensions: 1.875 x 1.875 x 4.5mm.     ----------------------------------------------------------------------------------------------------------------------------                                                                                                      Generating voxel specific head motion for /home/alistair/Documents/dparsftest/RealignParameter/3994A/rp_aimg001.txt finished.

I thinks it's the problem of your DPARSFA setting (i.e., missed "Segmentation/New Segmentation+DARTEL"). Please paste a snapshot here.

I do not wish to use T1 information. But, what are the benefits? 

I gather that T1 files are compulsory if it use to wish the preprocessing steps of DPARSFA. I have been able to do the pre-processing within the original DPARSF, and extract functional connectivity matrices via DPARSFA.


If you want to do it as basic edition (without T1 image), you need to do nuisance regression after spatial normalization (Course Part III).
