The error threshold for peptide spectrum matches was set to a 1% false discovery rate (FDR). Protein expression was measured by the total of identified spectral counts normalized by the total number of spectral counts in each MS run in order to adjust for the variation in signal across runs.
Proteins that showed increased expression in mev-1(kn1) comparing to in N2, according to liquid chromatography and mass spectrometry analysis.

- WBPaper00035227:bio-electrospray_regulated
Differences between treatments were visualized by principal component analysis (PCA) plotting with MeV/TM4. Data were initially filtered out for missing values and then subjected to a CLEAR test that combines differential expression and variability using the GEPAS web server at http://www.gepas.org. In our case, the false discovery rate was set to a stringent level of 5 per cent.

Intensities of spot features annotated as Bad or Not Found in the .gpr files were set to 1 to be removed from further analysis, and all of the six processed .gpr data were converted to .mev file with TIGR ExpressConverter ver. 1.7. The .mev files were processed with TIGR MIDAS ver. 2.19 with parameters set as follows: one bad channel tolerance policy as generous, with both of channel flag checked and background unchecked. The data were normalized by lowess normalization with default settings and with block and slide SD regularization. Authors then calculated log2(ASER/ASEL) ratios for each gene on the microarray. For the two pairs of dye-swapped repeats, authors calculated the mean log2(ASER/ASEL) of each repeat, so that up to four log2(ASER/ASEL) values per spot were obtained. Authors then calculated the percentile rank for each gene. Each gene spot detected more than once (18 847 spots) were subjected to MannWhitneys U test to assess whether its percentile rank values are significantly higher compared to the rest of the genes detected in the same experiments. Resulting significance levels are shown by P-values. From the P-values, false discovery rate (FDR) was further calculated by the Benjamini and Hochberg method. Statistical analyses were done by using R software version 2.9.
