The phrase "a threshold was determined" is correct and usable in written English.
It can be used in contexts where a specific limit or point of reference has been established, often in scientific, technical, or analytical discussions.
Example: "After extensive testing, a threshold was determined for the acceptable levels of pollutants in the water supply."
Alternatives: "a limit was established" or "a benchmark was set."
A threshold was determined in each block by varying the offset size by an adaptive staircase method (PEST; [21]).
Once a threshold was determined we exclusively considered the positions in the assemblies above the threshold as follows.
The DAB and haematoxylin channels were isolated using a plugin and a threshold was determined for quantification.
Based on peak intensity, a threshold was determined by BPS to classify the root node into two child nodes.
At such dose, a threshold was determined as the mean between the lowest p-STAT5 value of the JMML samples and the highest of the non-JMML samples.
A histogram was generated on the active window region and based on the mode (most repeated value, peak of the histogram) a threshold was determined.
Instead, we employed an adaptive thresholding approach in which a threshold is determined at each pixel based on some "local" statistics of the neighboring pixels.
After applying the masks, flagged pixels are counted and a threshold is determined through the cross validation phase under the receiver operator curve (ROC) criterion to classify the VT and VF trajectory images.
As part of this study, a threshold is determined for the optimum amount of abrasive charge that should be used in the tests to obtain maximum material loss regardless of the geological make-up of the aggregate.
A threshold is determined to identify the frequently occurring features among the four filter methods and set to 3 (i.e. T = 3).
The relative amount of gene-specific mRNA to housekeeping gene was calculated using 2−ΔΔCt, where Ct, the number of cycles at which amplification reaches a threshold, is determined using SDS software version 1.3.
