[…] in fig. , although few connections are missed, it can be observed that several spurious pathways were indeed identified., functional mri data was generated via realistic simulations, using the simtb toolbox, so that nodes belonging to the same sub-network share a common activity pattern (see section 4). similar to brain data, the correlation-based functional network, illustrated in fig. , […]

[…] of the proposed fmica model, was validated on the simulation data, task-related fmri data and resting-state fmri data. the details of the designed experiments were presented as follows., the simtb toolbox (; allen et al., ; erhardt et al., ) was used to generate simulation dataset including 20 subjects. each subject data was with v = 148 × 148 voxels, 12 […]

[…] inaccurate number of components for computation (experiment 2), and spatially subject-unique sources (experiment 3). in each experiment, we simulated fmri-like data of multiple subjects using the simtb toolbox (allen et al., ; erhardt et al., ). the number of subjects m was simulated to be 10. for each subject, c source images (148 × 148 pixels) and their corresponding tcs (150 or less time […]

[…] commonly used estimation methods. in a more complex simulation experiment we simulate the variability of individual components and additional noises to examine the robustness of the algorithm. the simtb toolbox in matlab is a very convenient tool for such analysis. simulation 3 is performed using simtb to test the algorithm’s performance with different individual components and noise vectors., […]

[…] across groups/conditions (calhoun et al., )., the performance of ssica has been investigated in vahdat et al. (), using one-dimensional and two-dimensional simulated fmri-like dataset using simtb software (erhardt et al., ). in the current study, we aim to test the validity of the ssica method on real fmri datasets, therefore evaluating for the first time the performance of ssica […]
