DPARSF is based on some functions in SPM and REST. Here, we have developed a MATLAB toolbox called Data Processing Assistant for Resting-State fMRI (DPARSF) for “pipeline” data analysis of resting-state fMRI. Hence, user-friendly toolbox for “pipeline” data analysis of resting-state fMRI would be very necessary. These manual procedures may be time-consuming and may increase the possibility of inadvertent mistakes. In SPM, the parameters need to be set step-by-step and subject by-subject. Although SPM is a powerful tool, lots of complicated and time-consuming operations are needed when analyzing large sample data set. The data could be preprocessed by SPM and then entered into REST’s analysis. As an easy-to-use MATLAB toolbox, REST is compatible with Statistical Parametric Mapping 2 (SPM). All the aforementioned methods could be calculated by a toolbox Resting-State fMRI Data Analysis Toolkit 1 (REST). ) and the fractional ALFF (fALFF, Zou et al., 2008 ), the amplitude of low-frequency fluctuation (ALFF, Zang et al., 2007 While FC measures the signal synchrony among remote brain areas, the regional spontaneous activity could be examined by several metrics, such as the regional homogeneity (ReHo, Zang et al., 2004 In addition, resting-state fMRI is also a convenient way for clinical studies since it has advantages of reasonable spatial and temporal resolution and non-invasiveness, as well as its simplicity that does not need to set complicated cognitive tasks.įunctional connectivity (FC) is widely used in resting-state fMRI studies ( Biswal et al., 1995 Resting-state fMRI is considered as a powerful tool for investigating the spontaneous neuronal activity which consumes most of the brain’s energy ( Fox and Raichle, 2007 (1995)įirstly reported the presence of spatially coherent activity in the resting-state blood oxygen level-dependent (BOLD) fMRI signal. Resting-state functional magnetic resonance imaging (fMRI) has been more and more widely used since Biswal et al. In addition, users can also use DPARSF to extract time courses from regions of interest. DPARSF can also create a report for excluding subjects with excessive head motion and generate a set of pictures for easily checking the effect of normalization. ![]() After the user arranges the Digital Imaging and Communications in Medicine (DICOM) files and click a few buttons to set parameters, DPARSF will then give all the preprocessed (slice timing, realign, normalize, smooth) data and results for functional connectivity, regional homogeneity, amplitude of low-frequency fluctuation (ALFF), and fractional ALFF.

However, user-friendly toolbox for “pipeline” data analysis of resting-state fMRI is still lacking. Resting-state functional magnetic resonance imaging (fMRI) has attracted more and more attention because of its effectiveness, simplicity and non-invasiveness in exploration of the intrinsic functional architecture of the human brain.
