  Transcripts of coding genes that showed significantly decreased expression in muscle. DESeq2 (version 1.24.0). Transcripts with a false-discovery rate adjusted p-value less than 0.05 were considered significantly differentially expressed. WBPaper00062325:muscle_depleted_coding-RNA
  mRNAs that showed decreased expression in 1 cell mebryo comparing to in oocyte, according to RNAseq analysis. Gaussian error propagation. As cutoff for the up-regulated genes authors used log2 fold change > 1 and P < 0.05 and as cutoff for the down-regulated genes authors used log2 fold change < -1 and P < 0.05. WBPaper00045420:fertilization_downregulated_transcript
  Neuronally enriched transcripts according to a comparison of neuronal nuclei IP samples to total nuclei using isolation of nuclei from tagged specific cell types (INTACT) technology. DESEQ2, fold change > 2 and FDR < 0.01. WBPaper00062103:neuron_enriched
  Transcripts that showed significantly increased expression in ogt-1(ok1474) neuronal cells isolated by FACs comparing to in FACs isolated neuronal cells from wild type. DESeq2, fold change > 2, FDR < 0.05. WBPaper00066485:ogt-1(ok1474)_upregulated_neuron
Bacteria infection: Enterococcus faecalis Genes with increased expression after 24 hours of infection by E.faecalis Fold changes shown are pathogen vs OP50. For RNA-seq and tiling arrays, log2 fold changes between gene expression values of infected versus uninfected nematodes were calculated. For log2 fold changes > 0.00001 the values > 81.25th percentile were defined as up-regulated and for log2 fold changes < -0.00001 the values < 18.75th percentile were defined as down-regulated. WBPaper00038438:E.faecalis_24hr_upregulated_TilingArray
  Maternal class (M): genes that are called present in at least one of the three PC6 replicates. A modified Welch F statistic was used for ANOVA. For each gene, regressed error estimates were substituted for observed error estimates. The substitution is justified by the lack of consistency among the most and least variable genes at each time point. Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest. A randomization test was used to compute the probability Pg of the observed F statistic for gene g under the null hypothesis that developmental time had no effect on expression. P-values were not corrected for multiple testing. [cgc5767]:expression_class_M
  Strictly maternal class (SM): genes that are the subset of maternal genes that are not also classified as embryonic. A modified Welch F statistic was used for ANOVA. For each gene, regressed error estimates were substituted for observed error estimates. The substitution is justified by the lack of consistency among the most and least variable genes at each time point. Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest.

P-values were not corrected for multiple testing. [cgc5767]:expression_class_SM
  Germline-intrinsic transcripts. Comparisons were made between genotypes by subtracting the mean log value of one ratio from another, and the significance of the difference was evaluated using Student t-test for two populations. For the fem-3(gf) versus fem-1(lf) direct comparison, authors performed the same analysis, except they used a Students t-test for one population. Author chose a combination of a twofold difference with a t value exceeding 99% confidence (P < 0.01), because these criteria allowed the inclusion of essentially all genes that had previously been identified as germline-enriched in a wt/glp-4 hermaphrodite comparison. Additionally, requiring a twofold difference reduced false positives, as the number of genes with two-fold difference and a P<0.01 only included ~100 genes more than with P < 0.001, and almost all genes showed germline expression by in situ hybridization.

Bacteria infection: Serratia marcescens Genes with increased expression after 24 hours of infection by S.marcescens Fold changes shown are pathogen vs OP50. For RNA-seq and tiling arrays, log2 fold changes between gene expression values of infected versus uninfected nematodes were calculated. For log2 fold changes > 0.00001 the values > 81.25th percentile were defined as up-regulated and for log2 fold changes < -0.00001 the values < 18.75th percentile were defined as down-regulated.

  Transcripts down regulated in hpl-2(tm1489) embryo comparing to N2 in tiling array analysis. Oligos from the tiling array were mapped to chromosome coordinates of the exons from Wormbase WS180. Any oligo that mapped to a gene on both the Watson and Crick strands was excluded. The remaining oligos were then grouped together (perfect match and mismatch) into probe sets and written out into an Affymetrix CDF file. The CDF file was converted into an R-package and loaded into R. The expression values were calculated using the justRMA function from Bioconductor. This used a Benjamini and Hochberg false discovery rate correction. WBPaper00040560:hpl-2_embryo_downregulated
  Genes expressed in N2. Expressed transcripts were identified on the basis of a Present call in 3 out of 4 N2 experiments as determined by Affymetrix MAS 5.0. WBPaper00025141:N2_Expressed_Genes
  Genes that showed expression levels higher than the corresponding reference sample (embryonic 24hr reference). A Mann-Whitney U test with an empirical background model and FDR correction for multiple testing was used to detect expressed transcripts (Benjamini and Hochberg 1995). Genes and TARs with an FDR <= 0.05 were reported as expressed above background. Authors detected differentially expressed transcripts using a method based on linear models. Genes and TARs were called differentially expressed if the FDR was <= 0.05 and the fold change (FC) >= 2.0. To more strictly correct for potential false-positives resulting from multiple sample comparisons, authors divided individual FDR estimates by the number of samplesor sample comparisons, respectively. This resulted in an adjusted FDR of 1.3 * 0.0001 for expression above background and of 7.4 * 0.0001 for differential expression. Authors called genes selectively enriched in a given tissue if they met the following requirements: (1) enriched expression in a given tissue (FDR <= 0.05 and FC >= 2.0), (2) fold change versus reference among the upper 40% of the positive FC range observed for this gene across all tissues, and (3) fold-change entropy among the lower 40% of the distribution observed for all genes.

  Coexpression clique No. 211, srj-42-srw-113, on the genome-wide coexpression clique map for the nematode GPL200 platform. All available microarray datasets for the GPL200 platform (Affymetrix C. elegans Genome Array) were obtained from the GEO repository. This included 2243 individual microarray experiments. These were normalized against each other with the software RMAexpress (Bolstad, 2014). Based on these normalized values, Pearsons correlation coefficients were obtained for each probe-probe pair of the 22,620 probes represented on this array type. The resulting list of correlation coefficients was then ranked to generate the ranked coexpression database with information on each probe represented on the GPL200 platform.

  Genes predicted to be upregulated more than 2.0 fold in rde-3(r459) mutant worms as compared to wild-type animals (t-test P-value < 0.05). A t-test (5% confidence) was applied to the triplicate sample data for each transcript in each mutant to identify genes significantly elevated or decreased compared with the wild type. WBPaper00027111:rde-3(r459)_upregulated
  Genes predicted to be upregulated more than 2.0 fold in rrf-1(pk1417) mutant worms as compared to wild-type animals (t-test P-value < 0.05).

WBPaper00027111:rrf-1(pk1417)_upregulated
  Genes that showed higher expression level in ASER than in ASEL neuron by mRNA tagging. 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. WBPaper00035424:ASER_up
