Sentence examples for thresholds cluster size from inspiring English sources
Peak coordinates of regions that showed connectivity with the PCC were identified for all analyses using cluster reports with the following thresholds: cluster size = 80 voxels (0.64 ml), minimum distance between peaks = 1 cm, and a BSR equivalent to a two-tailed p value of 0.001 (i.e., BSR = 3.3).
By thresholding cluster sizes rather than pixel values to reject false positives, this approach enhances statistical power.
The original fraction of the 26 981 BF clusters among all clusters is a mere 0.5%, while the fraction following the minimal thresholds of cluster size >10 and LT >0.5 is 3.5%.
If the streaming capacity of a cluster complies to the threshold, the cluster size remains unchanged.
Measurements include tracking efficiency, charge sharing, time over threshold and cluster size distributions as a function of incident angle for IBL 3D design sensors.
This threshold and cluster size within a given ROI was chosen to help reduce noise, hence avoid the detection of spurious activations in isolated voxels.
Threshold correction was performed by using AlphaSim program (parameters were as follows: individual voxel p = 0.01, 1000 simulations, FWHM = 4 mm, with mask) in the REST software, which applied Monte Carlo simulation to calculate the probability of false-positive detection by taking into consideration both the individual voxel probability thresholding and cluster size [ 34].
The map was constrained using a voxel-level minimum statistic threshold and a cluster size threshold.
The group-level statistical parametric maps were constrained using a voxel-level minimum statistic threshold, and a cluster size threshold.
For each of the investigated SNP, voxel-by-voxel group comparisons were made using SPM99 (Welcome Functional Imaging Laboratory, London, United Kingdom) using proportional scaling, setting the height threshold at P≤0.001 and cluster size threshold at >100 voxels, and including group (C-LHPA vs. LPA) as a covariate.
The AlphaSim program provides an overall significance level achieved for various combinations of cluster size thresholds and probability thresholds for each voxel [ 30].
