Sentence examples for group ica from inspiring English sources
'group ica' is not correct and usable in written English
If you are referring to a particular group (such as a student organization or club), you should use the full name. For example, "The members of the International Creative Arts Group (ICAG) are attending the conference."
We performed an independent component analysis (ICA) by using the "group ICA" function included in the fMRI toolbox (GIFT version 1.3h; http://icatb.sourceforge.net) developed for the analysis of fMRI data [ 38- 40].
The group ICA performed here is different to the ICA MELODIC analysis conducted during pre-processing as it identifies regions of concurrent activity across all participants rather than for individual participants (Beckmann & Smith, 2004).
Single-subject and group-level ICA was carried out respectively with the fastICA and the self-organizing group ICA [sogICA] algorithms [13].
Group clustering resulted in resting-state networks (RSNs) of known functional relevance that show resemblance with recently reported resting-state group ICA results.
Several intergroup and intragroup metrics are proposed for assessing the utility of the components for comparisons of group ICA data.
To compare the LDSTM components with ICA, PICA was performed by multi-session temporal concatenation group ICA (using MELODIC in FSL).
From the group ICAs, we identified five significant independent component patterns of interest (i.e., RSNs) that were common to both of the task conditions (Figure 2).
Before testing for possible mood state-related changes in the functional connectivity pattern of the five common RSNs, we examined the relative stability of this measurement by performing a simple split-half analysis of both of the datasets, repeating the procedure of the original group ICAs.
Figure 6 (top) shows an example of a group ICA-based [ 59] parcellation and also an example of the FNC, or among-network connectivity (bottom) both within healthy individuals (bottom left), schizophrenia patients (bottom middle) and differences (bottom right).
The whole-group ICA of MEG theta-band activity successfully identified left- and right-lateralized hippocampal networks (Supporting Information Fig. 1A), confirming that hippocampal theta-band network activity can be observed in the resting state.
This allow, a) to separate fMRI data sets using the group-ICA spatial maps in a linear model fit against, resulting in matrices (time-course matrices) describing the temporal dynamics for each component and subject, and b) estimate subject-specific spatial maps using these time-course matrices.
