Releases for Time-Frequency Toolkit

Development branch for new features.
Compatible only with Igor 6.10 - main feature that requires Igor 6.10 is implementation as an independent module.

Because of the independent module implementation, this version will not run in Igor 6.03. There may also be issues with previously created TFPlot windows: if these are unresponsive, close the window and recreate it.

Although this is still compatible with Igor 6.02, the experience is much better on 6.1. This adds some fixes for compatibility with 6.02/6.03. Expect future releases to be targeted to 6.1

Changes:

Changed default window size for cross platform compatibility

Fixed help button - didn't work with some tabs

IndependentModule disabled the BeforeExperimentSaveHook, so commented out IndependentModule pragma
-to be fixed in a future version of Igor

Collected controlbar preference controls into single Misc popup menu

workaround for auto-scrolling of waveselector listbox

now avoids "cooperative multitasking" for controls, and corrects control state if user is too quick

kludged margins on Igor 6.03 - experience is far better with 6.1, though

The functionality and code structure in this release are expected to remain stable.

Major rewrite of package manipulations folder structure.

Addition of a Noise Model tab with white and red noise model options and extensibility for other noise models.

Multi-Taper spectral estimate

fixed scaling and added options: magnitude/magnitude squared/sin amplitude/background normalized

numerous minor fixes

 

fixed bug in updating plot when frequency/period axes scaling was changed
cosmetic changes

procedure files were not included in the demo on last release

With this version, the user interface and organization of code will be pretty stable for a while. In future updates, I'll concentrate on implementing the Multi-Taper method, fixing some problems with the Lomb methods for XY data, and better noise model choices and confidence intervals.

I think I've caught all the bugs I introduced while reorganizing things, but until I've gotten feedback from other users I'll leave this as a beta release.

popup sort options for wave selectors
put buttons in controlbar for help and showing/hiding wave selection
allow switching position of data series/spectrum plots
SSA support will be put in future SSA package
Better ticks for reciprocal axis when linear frequency/period is selected
padding to get desired frequency resolution

preliminary support for extensible tabs
moved tuning procedure to age model package
Welch Lomb periodograms
added evolutive FFT
added Spline interpolation
reworked BlackmanTukey calculation

Includes a demo experiment that should ease the learning curve for using the package.

fixed tapered periodogram amplitude
added optional tapers to Lomb periodogram
substantially revised user interface

The previous was missing a necessary procedure file. Eventually I'll get the hang of this.

This is an initial release for testing. There's a list of bugs and feature requests at the bottom of the help file. Eventually I will transfer these to the IgorExchange issue area.

This release should be useful if used skeptically; it should work as advertised, but since so far only one person has ever used the package I'll be interested to see what other users have to say.
