Newest Igor User Contributions are at Igor Exchange
New user contributions are available on the WaveMetrics forum and project web site www.igorexchange.com.
User contributions there are divided into "projects" and "snippets":
- Code snippets are pieces of code (usually short and simple) that serve a specific purpose. Larger pieces of code with multiple functions, etc. should usually be created as a project instead.
- Packages include individual Igor procedure files or collections of Igor procedure files that are related, as well as external operations (XOPs).
User Contributions at the FTP Archive
Before there was the Web, there was only FTP for sharing files such as Igor experiments, XOPs, and procedure files.
Enterprising Igor users offered their solutions for loading specialized data formats and procedures for specialized data analysis, and uploaded them to the User Contributions directory of the now-closed Igor FTP site. Most of those files have been moved to the WaveMetrics FTP Archive.
Please note that many of these solutions are tightly linked to the period in history when they were developed; they worked with the versions of Igor they had at hand and may not work at all with modern Igor versions unless revised.
The User Contributions files are downloadable here.
