Pre-built packages are available for a number of common linux distributions. Detailed instructions on how to install OSIV may be found in the Users Guide.
Note that in order to install OSIV, the following libraries must be installed to your system: the TIFF library, the PNG library, and the FFTW library. Many distributions provide pre-built binaries for these libraries. If such packages are available for your operating system, then these should be preferred.
Important: In previous versions of the OSIV Suite, the vector positions in the output were given using the same conventions as the grid parameters of the input. Specifically, positions were given in terms of the upper-left corner of the corresponding interrogation window. While this was the intended and documented behavior, it resulted in unnecessary confusion. Consequently, as of version 2.1.2, vector positions in the output are given in terms of the center of the corresponding interrogation window. The grid parameters continue to be specified in terms of the upper-left corner of the interrogation window. If you relied on the previous behavior, please update your scripts accordingly.
