CHANGES IN VERSION 1.14.5 ------------------------- BUG FIXES o Reset plot layout after networkPlot. o Issue warning instead of error in writeFilesForKiwi when gene-level statistics are not p-values. This means that the GLS file will not be generated, but the GSS and GSC files are. CHANGES IN VERSION 1.14.3 ------------------------- BUG FIXES o Required functions from the snow package, used by snowfall, are now properly loaded. CHANGES IN VERSION 1.14 ----------------------- NEW FEATURES o Added new GSA method fgsea (fast GSEA) from the fgsea package. o Added max method as an option in consensusScores(). IMPROVEMENTS [credits to Alexey Sergushichev] o Updated the p-value calculation (while using gene permutation) from: sum(background >= value) / length(background) to: (sum(background >= value) + 1) / (length(background) + 1) where bakground is a vector of permuted gene-set statistics and value is the actual calculated gene-set statistic. This change avoids returning p-values = 0, instead the theoretically smallest possible p-value will be determined by the number of permutations used. E.g. for nPerm = 10000, the smallest p-value will be 1 / 10001 = 9.999e-05. o Improved speed of checkLoadArg(). o Improved speed of gene-set statistic calculation for GSEA in calcGeneSetStat(). o Improved speed of FDR calculation for GSEA in fdrGSEA(). BUG FIXES o Updated NAMESPACE to load dependencies in a better way. o Updated the parsing of sbml files in loadGSC(). o Updated networkPlot() to conform to changes in the igraph package. CHANGES IN VERSION 1.12 ----------------------- o No changes CHANGES IN VERSION 1.10.2 ------------------------- DOCUMENTATION o Updated the vignette R code to avoid an error in the call to biomart throught the getBM function. CHANGES IN VERSION 1.10.1 ------------------------- BUG FIXES o Fixed a bug in runGSA which returned wrong numbers for the up- and down- regulated genes, for the GSEA method. CHANGES IN VERSION 1.8.2 ------------------------- BUG FIXES o Updated loading of suggested packages from using require() to requireNamespace() instead. CHANGES IN VERSION 1.6.2 ------------------------- BUG FIXES o Fixed a bug in loadMAdata so that normalizing using MAS5 is now returning log2-transformed expression values. CHANGES IN VERSION 1.6.1 ------------------------- DOCUMENTATION o Updated this NEWS file CHANGES IN VERSION 1.6.0 ------------------------- NEW FEATURES o Added a function writeFilesForKiwi() that enables a seamless integration of the output from a gene set analysis with piano to the network-based visualization offered by the python tool Kiwi. CHANGES IN VERSION 1.4.2 ------------------------- BUG FIXES o Fixed a bug in loadMAdata so that mas5 can now be used for normalization. CHANGES IN VERSION 1.4.1 ------------------------- BUG FIXES o Fixed a bug in GSAsummaryTable which returned an error in the case of analyzing only a single gene set. CHANGES IN VERSION 1.4.0 ------------------------- NEW FEATURES o Added argument plot to consensusHeatmap() so that drawing the heatmap can be suppressed but the corresponding numerical matrix can be saved. o Added argument cellnote to consensusHeatmap() so that the information inside each cell of the heatmap can be chosen to be either the consensus scores (as previously), the median p-values, the number of genes or empty. o Added a matrix nGenesMat to the output of consensusHeatmap() containing the same information as printed in the heatmap if argument cellnote="nGenes". o Added arguments columnnames, colorkey, colorgrad and cex to consensusHeatmap() for better control of the column labels, toggling of the colorkey, color selection and text size. o Introduced the new function GSAheatmap(), which is similar to consensusHeatmap() but for only a single gene set result (gsaRes object). BUG FIXES o Fixed a bug which for some settings of runGSA would not output number of up- and downregulated genes in the gene sets. DOCUMENTATION o Updated consensusHeatmap() man page according to new changes in the function. o Added man page for GSAheatmap(). CHANGES IN VERSION 1.2.12 ------------------------- DOCUMENTATION o Updated the biocViews field in the DESCRIPTION file. CHANGES IN VERSION 1.2.11 ------------------------- BUG FIXES o Fixed a typo in the code which made it impossible to execute runGSA successfully with the option sample permutation.

CHANGES IN VERSION 1.2.9 ------------------------- BUG FIXES o Fixed a bug in consensusHetmap() so that the adjusted p-values are actually used if adjusted=TRUE. CHANGES IN VERSION 1.2.8 ------------------------- BUG FIXES o Fixed bug in diffExp() that in rare cases failed to output the vennMembers. CHANGES IN VERSION 1.2.7 ------------------------- BUG FIXES o Changed so that argument cutoff in consensusHeatmap() can be set to an arbitrarily high number (e.g. Inf) to easily include all gene sets. CHANGES IN VERSION 1.2.6 ------------------------- BUG FIXES o Fixed bug in loadMAdata() that removed duplicate entries in the annotation in an incorrect way. CHANGES IN VERSION 1.2.5 ------------------------- BUG FIXES o Fixed bug in diffExp() that returned incorrect gene IDs for $pValues and $foldChanges if and only if annotation was previously supplied to loadMAdata() AND the probeset IDs in the normalized data ($dataNorm) were unsorted. The $resTable is unnaffected. CHANGES IN VERSION 1.2.4 ------------------------- BUG FIXES o Fixed bug in the volcano plot in diffExp() for coloring points black. CHANGES IN VERSION 1.2.3 ------------------------- BUG FIXES o Improved error checking of supplied annotation in loadMAdata(). o Improved error checking of chromosome mapping in polarPlot(). o Fixed typo in loadMAdata man page.

Now a correct error message is given. CHANGES IN VERSION 1.2.0 ------------------------- NEW FEATURES o Added argument ncpus to runGSA(). Enables parts of this function to run in parallel, thus decreasing runtime. Requires R package snowfall. o Added function runGSAhyper() to perform gene set analysis using Fisher's exact test, as an alternative to runGSA. o Added information about genes in each area of the Venn diagram in the output of diffExp(). o Added volcano plot as optional output of diffExp() and added argument volcanoFC. o Added argument ncharLabel to networkPlot() and consensusHeatmap() to control the length of the labels in the plots and add the option to not truncate them. o Added the yeast metabolic model iTO977 to be loaded with loadGSC(), for detecting reporter metabolites using gene set analysis. (See vignette.) o Added support for running networkPlot() on objects returned by runGSAhyper(). DOCUMENTATION o Minor updates to the vignette. o Updated diffExp() man page. o Restructered this NEWS file. BUG FIXES o Updated diffExp() to handle changes in lmFit() and topTable() from limma. o Removed suppressWarnings(), as temporarily introduced in version 1.0.1, in polarPlot() around the calls to radial.plot() since warnings are now fixed in package plotrix. o Updated the main legend of the plot from consensusScores() to make it clearer. o Updated error-messages in networkPlot(). o Fixed typo in PC variance plot produced by runQC().

CHANGES IN VERSION 1.0.0 ------------------------- NEW FEATURES o Now part of Bioconductor. o Removed the arguments 'venn', 'heatmap' and 'polarPlot' from diffExp and replaced them with a new argument: 'plot'. o The consensusScores function now does not return its result invisibly. o The argument order in consensusScores has changed: 'plot' has been moved from last place to after 'method'. o Removed contrastName as output from runGSA and geneSetSummary, including man pages. o Changed name of folder for example data from exampleData to extdata, and updated man pages and vignette. o Changed so that total number of gene-level statistics are printed during run, instead of total number of unique genes. DOCUMENTATION o Added citation DOI to vignette. o Updated the man page for consensusScores, added correct output description. o Updated the Description field text in the DESCRIPTION file. o Changed the man page for consensusHeatmap clarifying that the cutoff argument is consensus score (not rank) o Updated the man page for loadGSC, clarifying the input. o Reworked the vignette to fit Bioconductor, removed section on R introduction. o Removed 'typical usages' section from man page of loadMAdata since this is covered in the vignette. o Updated the examples for diffExp, networkPlot, consensusHeatmap and consensusScores to show how to handle the returned object. o Added CITATION file. o Added NEWS file. o Added more links to similar packages in runGSA help page. o Updated the installation instructions in the Vignette to fit Bioconductor.
