• ‘Current Selection’ is now being preserved when using the suppressOptionsDialog option with the scripting Doc.SaveAs () method for MATLAB exports.
• Export MATLAB now uses the currently selected channels when exporting the selection unless the user explicitly overrode those by using the dialog.

New Features

LabChart 8.1.2 (Mac) now includes Preset Comments, one of LabChart’s most vital features for streamlining your laboratory procedure. Utilizing present comments, investigators can designate comments to be automatically entered for annotation of data. The comments can be initialized by keyboard shortcuts, digital inputs on the rear of some PowerLab models, the external trigger of a PowerLab, and the initiation of a LabChart stimulator protocol. Users can save time in typing each comment required for annotation, ensure accuracy in timing, and find more confidence in their results by utilizing this feature.
