Vicon SLF export plugin

At this time there is no MAC plugin to create slf files, only the Workstation one.  However, an slf file is simply a text file, and as such it is fairly straightforward to manipulate your data into an appropriate format starting with some sort of ASCII file and a bit of data manipulation.  Many users simply use an Excel workbook to do this; other users have also used Matlab or C++ to do similar sorting routines. An example Excel file that will do this is here:

In this example, first sheet is the exported data in an Ascii format.  Once sorted correctly, this then is simply read by cell into the second or third sheet.  Note that they are using 2 different marker sets; this example is from a motion capture set in which the subject had a base set of plugin gait markers, as well as clusters on the legs (4 markers each).  As such, the main makers are read into the first sheet, and the additional cluster markers are used to create an augment slf (it may take more, with the 15 markers/ augment slf size limit). You can take a look at the formulas for an idea of exactly how its working; you should be able to tweak this or create something similar to deal with whatever marker sets you intend to work with.  Once in the slf format, these sheets can be saved in a space-delimited text file (.prn).  Then just change the extension to .slf, and it should be ready to read into LifeMOD!
