摘要： Methods and systems for processing signals to minimize the effects of dye crosstalk. Deconvolution of multiplexed dye signals can include corrections for residual error determined from experimental measurements. Residual error corrections can account for reaction or assay specific factors and modify the subsequent filtering of signals. Correction values can be determined for specific dye-probe conjugates to minimize dye crosstalk and may be combined with residual error correction to further minimize errors in spectral deconvolution. Apparatus, systems, and computer-readable media can process signals and modify filters based on values obtained using the methods.

摘要： The present teachings comprise systems and methods for calibrating the background or baseline signal in a PCR or other reaction. The background signal derived from detected emissions of sample wells can be subjected to a normalized statistical metric, and be compared to a threshold or other standard to discard outlier cycles or other extraneous data. According to various embodiments, a relative standard deviation (relativeSTD) for the background component can be generated by dividing the standard deviation by the median of differences across all wells, where the difference is defined as the difference between maximum and minimum pixel values of a well. The relativeSTD as a metric is not sensitive to machine-dependent variations in absolute signal output that can be caused by different gain settings, different LED draw currents, different optical paths, or other instrumental variations. More accurate background characterization can be achieved.

摘要： Aspects of the present invention describe a method and apparatus for automating quality control for gene expression data. A computer based device receives gene expression data associated with a spectral species and genetic sample in each well of a plate. Gene expression data may be received from a sequence detection instrument performing one or more gene expression related operations for each of the wells of the plate. The computer based device identifies gene expression data determined to have anomalous characteristics according to a set of one or more quality control metrics and may conditionally flag one or more wells of the plate affected by the anomalous characteristics. Filters can then be selectively applied to temporarily or permanently remove the flagged data from subsequent gene expression studies.
