IGOR Pro is first and foremost a publication quality scientific and engineering graphics program. For example, image data can have x and y-scaling in physical units such as meters or arcseconds. While x-scaling is handy for vector data, matrices and higher dimensional objects can benefit from dimensional scaling as well. For example, the Fourier transform of a wave of time sampled data automatically creates a result with the correct frequency x-scaling. This not only saves memory and reduces clutter but it also allows IGOR to automatically use the x-scaling as needed. Normally, you would have to create a vector of data that contains x values, but in IGOR, you can simply specify x-scaling for a wave using two numbers. If you work with data with evenly spaced x values, you will appreciate IGOR's unique support for waveform data. String data can be of unlimited size and there are no limits on what it may contain, i.e., it may be binary. Signed and unsigned 8, 16 and 32 bit integer.Double precision floating point (64 bits).Single precision floating point (32 bits).Numeric data in waves may be real or complex with the following number types: Data and program files can also be external so that they may be shared among experiments. Experiments can be stored in a single disk file which can be easily exchanged with colleagues. Your data, graphs, tables, programs, notebooks and control panels for a given project are organized in a workspace called an experiment. With IGOR's Data Browser window you can navigate through the different levels of data folders, examine values of variables, strings and waves, and load data objects from other Igor workspaces (called experiments). You can efficiently organize your data into a hierarchy of IGOR's Data Folders in much the same way that you organize files in a hierarchy of folders on your hard drive. Unlike spreadsheet programs, IGOR's data objects need not clutter up your screen by being displayed in a table. Numeric variables may be real or complex and string variables, like string waves, are unlimited in size and may contain binary data. IGOR also supports another class of named data objects that store just a single number or string. Maintains additional information such as modification time, notes.Special support for waveform (equally-spaced) data.Two floating-point and six integer formats, strings.Number of data objects limited only by memory.Wave is short for waveform and emphasizes IGOR's unique support for evenly spaced data. IGOR Pro stores your data in named data objects called waves. You can drag files onto Igor and, if the type of the file is in question, you will be able to choose from a list of possible actions. Exporting, like importing, can be fully customized and automated. Processed data can be stored in IGOR files, exported as text or binary files, transferred to external programs via program-to-program communication methods, or transferred to another computer via FTP. Once your data is loaded into IGOR Pro, you can organize it in a hierarchy using the Data Browser. If you need to import data of a particular type from a particular source over and over again, you can use IGOR's programmability to customize and automate any of these import methods. Acquiring data from A/D cards and external instruments.Loading data from text and binary files of various formats.You can import data into IGOR Pro through many channels including: IGOR Pro provides a variety of import, storage and export capabilities that can handle almost any requirement. Scientists and engineers encounter many data formats.
