FLoSC was developed using a combination of software tools. More specifically,

• graphical user interface (GUI) was implemented using VBA in Microsoft Office Excel^TM;
• model fitting and computation are done behind the scene in R, a quality open-source software for statistical computing;
• communication between Excel and R is achieved by an Excel plug-in, RExcel, also an open-source software.

Note: R is released under the GNU General Public License (GPL), which permits all and any use of the package. For further description, see here.

The FLoSC installation program will install R, RExcel and all necessary R libraries automatically. In addition, the installation process will check whether all required Dynamic Link Library (DLL) as listed in the Downloads area are present in the operating system; if not, the missing DLLs will be installed and registered automatically.
