描述----------Description----------
A simulated dataset for testing purposes. m/z ranges from 800 to about 4000 Thomson, sampled at approximately 118,000 points. The isotopic patterns present in this artificial dataset exactly obey the Averagine model in combination with Exponentially Modified Gaussians peak shapes, s. fitModelParameters if no noise were present. The noise has been generated from two sources: the first is a baseline pattern of Gaussian bumps with low intensity and the second one is additive noise drawn from a truncated Gaussian distribution. The dataset contains about 300, partially heavily overlapping, peak patterns whose data are stored in data(toyspectrumsolution).
模拟数据集用于测试目的。为m / z范围从800到约4000汤姆森,在约118000点采样。在目前这种人工数据集的同位素模式完全服从指数修正高斯峰形,S Averagine模型结合。 fitModelParameters如果无噪音。噪音已产生两个来源:第一个是强度低,第二个高斯颠簸的基线模式是来自一个被截断的高斯分布的加性噪声。该数据集包含约300个,部分严重重叠,其数据存储在data(toyspectrumsolution)峰模式。
