 It is said that `imitation is the sincerest form of flattery`. This project emulates the popular [fslmaths](https://fsl.fmrib.ox.ac.uk/fslcourse/lectures/practicals/intro3/index.html) tool. fslmaths is a `general image calculator` and is not only one of the foundational tools for FSL's brain imaging pipelines (such as [FEAT](https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FEAT)), but has also been widely adopted by many tools. This popularity suggests that it fulfills an important niche. While scientists are often encouraged to discover novel solutions, it sometimes seems that replication is undervalued. Here are some specific reasons for creating this tool:
 
-1. While fslmaths is provided for without charge, it is not [open source](https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/Licence). This limits its inclusion in other projects, in particular for commercial exploitation.

 2. Using an open source license allows niimath to build with open source libraries that the FSL team can not use. Specifically, the CloudFlare zlib provides dramatically faster performance than the public domain library used by fslmaths. n.b. Subsequently, we helped update [CloudFlare zlib](https://github.com/cloudflare/zlib/pull/19) that allows recent FSL releases to use this library,  improving the speed for all FSL tools.
 3. Minimal dependencies allow easy distribution, compilation and development. For example, it can be compiled for MacOS, Linux and Windows (fsl can not target Windows).
 4. Designed from ground up to optionally use parallel processing (OpenMP and CloudFlare-enhanced [pigz](https://github.com/madler/pigz)).
