Unlimited undo/redo for all procedure code and notebook editing, and for most interactive graph and layout adjustments.Igor Pro 7 uses Unicode internally, improving the rendering of mathematical symbols and foreign characters.(32-bit applications are still available.) 64-bit architecture on both Windows and Macintosh allows increased memory usage and larger waves and datasets.The following are highlights of the new features we have added to Igor Pro 7 since version 6.3: Improved speed of displaying notebooks, help windows, and procedure windows.Drawing speed of graph traces on High-DPI displays under some specific circumstances is dramatically improved.Greatly improved the speed of creating and looking up waves by name when there are many similarly-named waves in a data folder.Igor Filter Design Laboratory (IFDL), which was previously a separate paid product, is now part of Igor Pro 8.New built-in Voigt and dblexp_peak fit functions, threadsafe ODR fitting with built-in parallelization.New Short-Time Fourier Transform (STFT) operation and seven other transformations.New Back and Forward buttons in procedure and notebook windows allow you to quickly navigate in these window types.Procedure windows and the command line now suggest options to complete the current command.New Box Plot and Violin Plot graph types make it easy to show the distribution of values within a data set.The redesigned Procedure Browser allows you to quickly find and filter symbols (functions, macros, etc).New Toolbar provides easier access to frequently used features.Object names are now limited to 255 bytes, versus 31 bytes in Igor Pro 7.The following are highlights of the new features we have added to Igor Pro 8 since version 7: Wide-Angle Neutron Spin Echo Spectroscopy.Fixed a bug in QLA_def_var when attempting to create a scalar string variable in netCDF-4 classic model files.Fixed an erroneous information message when creating a char dataset by commuting another datatype that stated that a dimension had to be created when one was already specified.Added storage=-1 option to QLA_def_var which will apply the most efficient storage method automatically depending on the dataset size. Implemented the option of using compact storage when defining a variable (QLA_def_var).To create a netCDF-3 use the netCDF API nccopy.exe to convert your netCDF-4 classic model into a netCDF-3 i.e. Only HDF5 based netCDF-4 files can be created directly.ipf is included which uses almost all the functions available that you can use to make your own netCDF-4 / netCDF-4 classic and figure out how it all works, test the files using ncdump, nccopy, or the included loader etc. Functions vaguely named after netCDF functions e.g.Functions follow similar syntax to netCDF C library functions.Provides some hopefully helpful error/information messages in the history area.Provides some basic help for keeping CF compliance.Keeps track of the hierarchy, duplicate names, dimensions size matching etc.Keeps track of unlimited dimensions, layout, and chunking.Keeps track of _Netcdf4Dimid and _Netcdf4Coordinates required hidden attributes.Switch between types easily without changing any code.Functions to create netCDF-4 or netCDF-4 'classic model' files directly from Igor.Menu is provided for convenience, inline is also perfectly fine.Function to determine the type of netCDF file.Functions to list, get, or set the attributes of a dataset.
