Details
详情----------Details----------
It eliminates signals that were not found. The filtering is based on the FLAG given by the AFE as follows: For a feature = xi accross all the samples, we demand that at least p spots for that feature, in at least one experimental condition, had a quantification flag denoting that the signal is found. A spot is considered Found if two conditions are true: 1) the difference between spot signal and the local background signal is more than 1.5 times the local background noise and 2) the spot diameter is at least 0.30 times the nominal spot diameter. A Boolean variable is used to flag found features. 1 = IsFound
它消除了没有被发现的信号。 AFE的如下标志：根据过滤功能=第十一accross所有样品，我们要求至少该功能的P点，至少在一个实验条件下，有量化标志表示该信号被发现。 A点被认为是发现，如果两个条件：1）现场信号和本地背景信号之间的差异是当地的背景噪音的1.5倍以上，2）光斑直径光斑直径至少0.30倍的名义。一个布尔变量用于标记的功能。 1 = IsFound
值----------Value----------
An RGlist with probes that are found (according to the correspondind AFE flag and the filtering options). It also writes an output file (IsNOTFound.txt) that contains probes that were filtered out because were NOT FOUND.
一个被发现的探针（根据的correspondind AFE的标志和过滤选项）RGlist。它还写到输出文件（IsNOTFound.txt），其中包含被过滤掉，因为找不到探针。
