mt_measures error: Error in points[1, ] : incorrect number of dimensions
We collected data from about 80 participants with no problems using mt_measures, but for some reason adding the 81st participant's .csv file leads to the following error when using mt_measures:
Start calculating deviations of actual from idealized response trajectory.

Error in points[1, ] : incorrect number of dimensions
Question 1) When I open the .csv in Excel, I don't see any obvious problems, and I'm not sure how to identify what might be wrong with the underlying .csv file based on the error message (dimensions of ___?).
Question 2) I'm also wondering how I can input custom coordinates for target locations (endpoints) to be used for calculating deviations from the idealized trajectory, and whether this might help. I see how to do this globally (i.e., if all targets had the same endpoint), but I'm wondering if it's possible to specify different endpoints by target (there are 15 different targets, each with a different ideal endpoint).
