Project Releases

Version 4.8-beta1:
This version of the "TA Data Analysis" procedure is required with the new IP7.

The "TA Analysis" procedure will work with both 32 and 64 bit versions of Igor Pro 7. It is also backward compatible with IP6 and fixes many bugs.

The old curve fitting procedures will only work with the 32 bit version of IP7. You will need to load "obsolete" MultiPeakFit extensions from new location (More Extensions --> Curve Fitting --> Obsolete). I will update them when/if the old ExpGauss functions migrate to IP7.

Hi all! Long overdue update. New in version 4.7:

• Support for updated Helios and EOS software, including updated data file and time axis formats.


• Greatly improved global analysis code.


• Bug fixes!!!

New in version 4.5:

• Added a function to export a processed data set in CSV format.



 

New in version 4.4:

• Added a function to combine two data sets which share either a common wavelength or time axis.


• Bug fixes related to wave naming so that the correct names are generated independently of the order in which you process a data set (time zero, chirp, scattered light corrections, etc.)


 

New in version 4.3.x:
 

• Fixed bug during import of data files in code that redimensions the data matrices by checking for monotonic wavelength data. Updated again for 4.3.1 to fix bug where the code looped if footer info was missing. Footer info restored in 4.3.2.


• Improved and expanded on chirp correction code.


• Began re-write of curve fitting code. Improved consistency and clarity for available functions.


• General code clean-up and bug fixes, particularly in wave handling and naming procedures.


• Better handling of 1D (row formatted) data files, e.g., kinetic info at a single wavelength.


 

Please send me email with feedback! It is very useful to know how and where this code is being used.

NEW IN VERSION 4.2.X series:

• Added fit function options to chirp correction routines.
• Bug fixes in chirp correction (interpolation) routines (times now derived from red end rather than blue end of data file).
• Fixed bug in "Load . . " that overwrote some files.
• Bug fixes in window hook code so that proper time or spectra axis is displayed.
• Code cleanup and more bug fixes.
• Began implementing automatic trace coloring for easy differentiation of visible waves.

NEW IN VERSION 4.2.5:

• Chirp correction routines.
• Fixed bug in "Load . . " that overwrote some files.
• Bug fixes in window hook code so that proper time or spectra axis is displayed.

• Chirp correction routines.
• Chirp correction routines.

NEW IN VERSION 4.2:

• Chirp correction routines.
• Chirp correction routines.
• Chirp correction routines.

NEW IN VERSION 4.1:

• Added a procedure for extracting a subset of the data (region of interest) directly from an image, using the cursors to define the limits. This is necessary for analysis procedures which require a "clean" set of data, such as singular value decomposition.
• Major work on providing User-friendly, consistent interface to Igor's singular value decomposition and global fitting routines.
• Many, many bug fixes.

The archive contains two procedure files, an experiment template with the adopted procedures, and pdf documentation.

NEW IN VERSION 4:

• This release implements a data visualization routine when data is imported. 1D data slices at Cursors A and B on your image will be automatically displayed for quick inspection.


• The "Extract . . . " routines have been re-written allow for averaging over a range of pixels in the vertical or horizontal direction (try putting both Cursor A and B on an image).


• Some of the matrix math has been re-written to take advantage of Igor's built-in indexing capabilities.


• Many, many, many bug fixes.
