Bioinformatics Genes and Pathway Analysis for Chronic Neuropathic Pain after Spinal Cord Injury

Figure 1

The background and signal value for each sample. Red represents the average of the values of the sample signals for each sample. Blue represents the average of the background values for each sample. It demonstrated that, after excluding the influence of background, the signal values of the samples are still high (a). The horizontal axis represents the name of samples, while the vertical axis represents the expression value after log conversion. The black lines stand for median, which can be used to identify the degree of standardization after normalization of all samples by the package of R/Bioconductor. It can be seen that the black lines were almost on the same line (b). Sample correlation calculated by injury associated genes expression. Both the horizontal axis and the vertical axis represent the name of samples. The gene expression level from different sample was calculated with Pearson correlation. The closer the point is to the blue color, the greater the correlation is between the two samples. It shows that the correlations of all samples are basically very strong (c).
