I found out because we ran out of licenses... K>> pos2dim3d(pos) License checkout failed. License Manager Error -4 Maximum number of users for Statistics_Toolbox reached. Try again later.

Error in pos2dim3d (line 39) dpos = zscore(abs(diff(pos,[],1))); 39 dpos = zscore(abs(diff(pos,[],1)));

What's even more interesting: the function is not called from anywhere ;-). pos2dim should be the one to go for, but this one also has a call to zscore...

updated on revision 9032: removed pos2dim3d and replaced zscore with manual computation (i.e. subtract mean and divide by std)

thanks :-) I was calling it from the debug command line, not sure which of the two to use.
