Updates 2021/01/07

The new Weka release prompted an update and some other changes that occurred during the crazy busy period before Xmas.


  • adams-spreadsheet: fixed a memory leak when generating and displaying lots of spreadsheets with the SpreadSheetDisplay sink.

  • adams-weka and adams-weka-lts: the attribute summary panel now displays min/max/mean/stdev for date attributes using the attribute's date format rather than as number of milli-seconds.


  • The ReportFileReader transformer can output reports as an array now.

  • Any variables in the extension option of the ReplaceFileExtension conversion get automatically expanded now.

  • adams-spectral-2dim-core: The SampleDataFileReader can output the sample data objects now as an array as well.

  • adams-weka: upgraded Weka to 3.9.5-fork-0.0.2

  • adams-weka-lts: upgraded Weka to 3.9.0-fork-0.0.12

  • adams-meka: upgraded to Meka 1.9.4


  • The Preview browser now has additional actions for local files: open, delete, print.

  • The CombineArrays and CombineCollections sources make it easy to combine multiple arrays/collections in storage to be combined into a single one.

  • The FileNameCompare comparator, which can be used with the Sort transformer, compares file-like objects, using only the name-part, ignored the path altogether. This allows interleaving files from multiple directories using their name alone.
