Scaffold perSPECtives 2.0.4 Release Notes (2014-0808)

Scaffold perSPECtives Features

Updated the Help system and the Users' Guide

Added support for precursor intensity quantitation.

Added the ability to read precursor intensity values provided in the title lines of MGF files or intensities specified in mzIdentML files.

Added log2 fold change to the Display Types.

Replaced the modified heat map of the previous version with a Samples Table Overview.

Added a Visualize View containing a true Heat Map.

Removed the expression profile clustering option which was replaced by the Heat Map.

Removed the option to perform expression profile coloring.

Added the ability to filter based on the p-value of an applied statistical test.

Apply thresholding and protein grouping during data loading.

Allow user specification of customized default parameters for thresholding and protein grouping during loading.

By default, when first loading data, the thresholds are as follows:

If the data has no decoys, the minimum number of peptides selected under the FDR option in the preferences tab, or MZID thresholds if that is selected in the preferences tab.

If the data has decoys, the default FDR levels shown in the preferences tab, or MZID thresholds if that is selected in the preferences tab.

When adding data to an existing file the default thresholds are as follows:

For existing data with decoys and an FDR threshold: the FDR thresholds are reapplied at the same levels, with the same minimum number of peptides.

For existing data (with or without decoys) with MZID thresholds: MZID thresholds are reapplied.

For existing decoy-free data with a minimum number of peptides threshold: When new decoy-free data is loaded, the threshold is reapplied at the same minimum number of peptides; AND When new data with decoys is loaded, FDR thresholds with the same minimum number of peptides and unbounded protein and peptide FDR is applied.

Indicate with parentheses calculated values that depend on missing values.

Improved the Experimental Design interface in the Configure Quantitative Analysis dialog.

Added new export reports and improved existing reports in the Export menu and in the right-click context menus.

Added the ability to export an Attributes file through the right-click context menu.

Display additional information in the Publish View including the perSPECtives version in which the data was thresholded or filtered.

Added the ability to hide columns through the right-click context menu.

Added failure notification to the Find function.

Added colors to indicate statistical significance levels.

Added colors to the View > Summarization menu.

Modified the display of spectral counts in the Peptides Pane to indicate if the count has been adjusted by invalidating peptides.

Renamed the Display Options control Color Options, removed the dropdown for selecting the coloring method. Each Display Type now has its own coloring method and the color options last selected for a specific Display Type become the default color selections for that Type.

Provide an informative message about available updates.

Added a warning about clustering on "any shared evidence".

Removed the Undo and Redo controls.

Activate and display the "clear all filters" icon when data is filtered on protein/accession number.

Made the program compatible with Java 7. Include Java 7 JVM in Mac Installer for compatibility with OS 10.9.
