SNC DDG Calculator


[Introduction] [Version History] [Download] [FAQ] [WaveMetrics]

Introduction
      SNC DDG Calculator is a patch data analysis tool developed for WaveMetrics Igor Pro versions 4 and higher. The entire program is contained in a single procedure file, which can be downloaded from this page. The main function of this program is to read in V_half and Slope values from Boltzman-fitted G-V curves and calculate DG and DDG values, average these values, and create graphs to represent the averaged DDG data. This program is still in active development, and new features/bug fixes are being addressed as they arise. If you use this program, you are encouraged to e-mail questions, comments and suggestions to [ s t e v e c @ q i g u a n g . n e t ].

Stable version released on 2003.09.28. All known bugs fixed and new features added:

  • Text data display now displays averaged Vh and Slope values.
  • Graphing of Z, Vh and Slope values is now available.
  • Sorting by "Name" has been replaced by "Sequence."
  • Sorting of graphs by "Max DDG" and "Min DDG" have been relabled "Ascending" and "Descending" and are now fucntional.
  • Issue with displaying SEM while using WT graphing options has been fixed.

0.1b  

This is the version that was demoed on 2003.09.17 and distributed to lab members via e-mail. There are several bugs and incomplete features. Known issues include:

  • Displays of averaged V_half and Slope values are not available.
  • Graphing of V_half, Slope and Z values is not available ("Other Graphs" button does not work).
  • In the "Create DDG Graphs" panel, sorting by Max DDG and Min DDG does not work.
  • In the "Create DDG Graphs" panel, concurrently selecting "Show SEM" and either "Divide by WT" or "Subtract WT" will result in an error.
  • In the "Create DDG Graphs" panel, the "Differentiate:" options have no effect. This feature may be dropped in future versions because the user can easily specify colors and patterns by double-clicking on the graph.
  • The "Restart" button doesn't completely reset the GUI. If you want to start over, just close the window and open SNC DDG Calculator again.
