Though we tried to overcome this limit by setting a threshold to lesion size (>10 voxels), this aspect could impact the estimations of average T2 values in small lesions.
For the remarkably dominant gradient (i.e., S 11/S 22≥T h where Th is a threshold to define the remarkably dominant gradient), this angle will be used to determine the pattern directions of the discarded pixel, which are horizontal, 45° diagonal, vertical, and 135° diagonal directions as shown in Fig. 7.

Given the HOCTAR performance relative to the first 50th percentile of prediction ranked lists, we decided to fix this as a threshold to consider bona fide target genes.
Since this matrix of ND is a weighted matrix where each entry represents the strength of interaction between the corresponding gene pair, we need to set up a threshold to obtain a connectivity matrix from this weighted matrix.
For patients initially on empiric fluconazole, we have a low threshold to broaden this empiric coverage in the event of persistent fever or radiographic suggestion of invasive fungal infection.
As the results show, 41.4% of the presented tags have received enough crowd's opinion to be considered valid or non-valid (difference between number of agreements and disagreements must be more or equal to a given threshold to be validated in this experiment we setup this value to 5).
