Expander version 6.0 includes the follwoing improvements: =========================================================== 1)Addition of Degas tool for network-based clustering 2)Addition of ISA algorithm for bi-clustering 3)Addition of an option to extract groups from hierarchical clustering (either by manual selection or according to tree node distance) 4)Support for similarity data (i.e. similarity dmatrix can be loaded as the main data file and clustered using hierarchcal clustering) 5)Added a "Differential expression filter results" view to the data view after applying SAM/t-test as filter methods. This tab contains the p/qvalues as well as fold-change information 6)Reduced waiting time for opening a single cluster view inside a clustering results visualization 7)Improved (significantly reduced) k-means runing time 8) Changed main menu so that all actions previously activated by "Export to text" items along with "Save Solution" items can now be operated from one item (File>>Export to text) 9) Remove the "Import file" option from the Load cel files dialod box. This option used to utilize the Aroma affymetrix package, and required temp directories to be generated by Expander. However, not all OSs support this and thus cause the entire operation to fail. The analysis can be performed by downloading cdf package from Bioconductor and using the "Use R package" option.
