Hello,
I'm struggling with coming to a solution for this particular problem. I have created a function that takes data from a .c3d file and creates a structure and substructure with normalized data for every joint, every plane of motion, maximum, minimum, etc...
Now, I have to save the result of this function with a particular name, automatically if possible. Among the input variables, I always call a file which has the name of a test subject inside (ex: dinamica_giovanni.c3d ). I would like to implement an automatic save with that name inside the function.
After that, I have to place some of this data, depending on different movements (1 to 8) to one in 4 holes (whack a mole structure) and then process the results through anova tests etc...
I would like to create a function that loads a particular name-based, saved data from the previous point and process the data.
The input variables I would like to use are: structure of the test subject, hole number where the mole spawned, movements. For example:
output = function(subject_name, 1, 7)
also in this case, i would like to save my data in a structure (can be the output variable) that collect data every time i run the function
here is function n.1
