| Hi list, I've adapted two of my MoCap scripts for matlab to interface with the MoCap toolbox. One script for plotting data from a potentially large number of markers, and another one for reading motion data from the Gesture Description Interchange Format. I have include some links, descriptions, and references below, in case anyone is interested to have a look. cheers, Kristian 1. mcmocapgram The function plots what we call a mocapgram of a mocap recording. XYZ position coordinates are normalised and projected onto an RGB space. Each marker is assigned a separate row. This gives a quite good visualisation recurring and periodic patterns in the recording.  direct link: references for mocapgrams: A. R. Jensenius, S. A. Skogstad, K. Nymoen, J. Torresen, and M. E.

Springer, Berlin Heidelberg, 2012. 2. mcreadgdif We have been recording motion data into SDIF files, using a toolbox developed for Max/MSP and Jamoma. The script "mcreadgdif.m" reads a data stream from these so-called "GDIF-files" and organises it into a MoCap Data structure. This means that practially any sensor data stream can be recorded as GDIF-files, and then imported into the Mocap Toolbox for analysis. references for GDIF / recording of motion data into SDIF files: A.
