IGOR Pro

IGOR Pro is an extraordinarily powerful and extensible graphing, data analysis, and programming tool for scientists and engineers.

• Journal-quality scientific graphs
• 3D and volume visualization
• Flexible image display
• Handles large data sets very quickly
• Extensive scientific and engineering data analysis
• Curve fitting, peak fitting
• Signal processing
• Image processing and image analysis
• Special support for evenly spaced data
• Completely programmable and customizable

The IGOR scientific graphing and data analysis program has been in active development since its introduction on Mac in 1988.

Academic and Student pricings are available, see this page for more information.

Changed Behavior

• The axis zero line now honors the gridEnab setting (for drawing between a % to b % of the plot area.)
• To set a fractional zero line using the Modify Axis dialog (in the Ticks and Grids tab) you need to enable the relevant grid. After that you can turn the grid off, leaving only the zero line.
• The areaXY and BinarySearch functions now tolerate leading and trailing NaNs in the input waves.

Bug Fixes

• Changed code for complex division to correct cases where the divisor contains INF.
• Corrected labels in StatsAnova2Test when the input data used dimension labels for the rows and the columns.
• SetIgorHook's hook functions are no longer forgotten when re-opening an experiment that set them, fixing a bug introduced in Igor 6.35.
• A relative include statement like #include ":folder:file" works even within a procedure file that has been included into an independent module.
• Fixed possible crash if you did a polynomial fit in a preemptive thread.
• The Display and AppendToGraph dialogs now avoid generating commands with more than 100 waves, which had provoked a "too many waves" error message.
• The hash string function no longer produces incorrect results when the input data contains one or more zero bytes.
• Fixed AppendImage/G=1 causing non-RGB image with cindex set presetting the Modify Image dialog to use color tables instead of color index waves.
• Macintosh: when a second instance of Igor is started, that second instance no longer automatically opens a copy of the first Igor's open experiment file.
• Macintosh: added SetIgorOption IgnoreMouseClicksWhileRunning = 1 to avoid rare crashes due to users bringing up dialogs while a function is running. It is off (0) by default, giving the same behavior as Igor 6.36 and earlier.
• Windows: The maximum number of user-defined submenus allowed (220) is now properly observed, preventing experiments from creating non-working user-defined submenu items. Note: the maximum number of user-defined submenus on Macintosh remains at 300.
• Windows: SetFileFolderInfo works with directories.
• Windows (64-bit): Improved the accuracy of the computations in Convolve and Correlate for very long single-precision float waves.
• Windows Igor J: Fixed a bug that caused the File Type popup menu to malfunction when invoked from the ImageLoad operation only.

Procedures

• WMImageInfo's WM_GetColorTableMinMax returns correct values for complex image waves.

XOPs

• Windows 32-bit only: Added an XOP for controlling settings of Axon (now Molecular Devices) MultiClamp 700B patch clamp amplifiers. See MultiClamp700xCommander XOP for details.
• Added the IgorGIS XOP, part of the IgorGIS Package that, among other things, loads data and attributes from geographic information system (GIS) vector and raster files into waves and variables. See IgorGIS Operations for the operations added by the IgorGIS XOP.
