2IGOR Pro使用方法
2.1数据导入方法
Igor Pro provides you with the ease and flexibility to import a wide variety of data file formats so you can concentrate on the important aspects of analyzing and displaying your data. The main data formats supported are:
∙Delimited text.
∙Fixed-field (FORTRAN) text.
∙General Binary.
∙Excel spreadsheet.
∙HDF.
∙HDF5.
∙Matlab.
∙JCAMP.
∙Nicolet Instruments.
∙SDTS DEM and DLG.
∙National Instruments TDM (DIAdem).
Igor Pro can import data as integer or single- or double-precision floating point numbers, import data in various common date and time formats, or import values simply as text.
Import a wide variety of image file formats to take full advantage of Igor Pro's Image Analysis capabilities:
∙GIF.
∙PNG.
∙JPEG.
∙PICT.
∙TIFF.
∙BMP.
∙PhotoShop.
∙Silicon Graphics.
∙Sun Raster.
∙Targa.
For multimedia and sound analysis, you can import sound data encoded in the following formats:
∙Audio Interchange File Format (AIFF & AIFF-C, Mac only).
∙Movie Audio Track (MooV, Mac only).
∙MPEG Audio Layer 2 (MP2, Mac only).
∙MPEG Audio Layer 3 (MP3, Mac only).
∙Waveform Audio File Format (WAVE, Windows only).
With Apple's QuickTime installed, you can not only create movies but can also extract individual frames.
You can also import data in Igor Pro's native file formats such as Igor Text and Igor Binary. You can easily view data stored in other Igor Pro experiments, using the Browse Experiment feature of the Data Browser, and import such data directly into your current experiment file.
Importing Data
Igor Pro's file loaders are accessed via the Load Waves submenu, which includes all of the built-in file loaders and other data importation facilities added via Procedures or XOPs.
You can load most common text file formats using Igor Pro's Load Waves dialog.
This dialog includes the Load Data Tweaks subdialog that you can use to specify any unus
ual aspects of the data you are importing.
The Load Waves menu also includes shortcuts, such as the Load General Text and Load Delimited Text items, that you can use to access the respective file loading routines with default options.
Programming Flexibility
If you need to go beyond the built-in file loaders and have a file format that Igor Pro cannot already import, then you have the flexibility of creating your own custom file loaders using Igor Pro's powerful built-in programminglanguage or by creating an plug-in module using the optional XOP Toolkit.
