Hi All,

We have been collecting data and running models through Vicon Nexus. We have been doing some signal processing/anlaysis by creating a c3d file in Nexus, and then opening that file in Datapac 2K2. Recently, for some inexplicable reason, Datapac is not reading c3d files on recently collected data (data from this time last year is still read without difficulty). We've contacted Vicon, and they have stated that there has been no change to the way they write c3d files. Run Technologies went out of business, so we can't contact them. We appear to be stuck.

Has anyone had similar difficulties? And if so, have you found a solution?

It appears as though we may need to find a new software solution to perform signal processing on a c3d file. Does anyone have any recommendations? We work with students who are primarily undergrad/inexperienced grad students.

Thanks in advance. As always, I will post a summary of replies.
