  Genes that showed expression levels higher than the corresponding reference sample (L3/L4 all cell 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.

  Genes with expression 1.5X depleted in PVD and OLL neurons. Data sets were normalized by RMA and transcripts showing relative PVD enrichment (>=1.5X) vs. the reference sample were identified by SAM analysis (False Discovery Rate, FDR < 1%) WBPaper00036375:depleted_in_PVD_OLL
  Transcripts that showed significantly increased expression in PVD neurons isolated from TV22833 wyIs840(ser2prom3::daf-12a(rh273)::gfpnovo2, Pmyo-2::gfp); wyIs592(ser2prom3::myr-gfp), comparing to in PVD neurons isolated from animals that only expressed wyIs592.

  Genes with expression enriched in PVD and OLL neurons. Data sets were normalized by RMA and transcripts showing relative PVD enrichment (>= 1.5X) vs. the reference sample were identified by SAM analysis (False Discovery Rate, FDR < 1%). Data sets were normalized by RMA and transcripts showing relative PVD enrichment (>=1.5X) vs. the reference sample were identified by SAM analysis (False Discovery Rate, FDR < 1%) WBPaper00036375:enriched_in_PVD_OLL
  Genes significantly enriched (> 2x, FDR < 5%) in a particular cell-type versus a reference sample of all cells at the same stage. 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 that show selective expression in a subset of cell types vs broadly expressed in many cell types. Correspond to 20% - 57% of enriched_genes for a given cell type.
