- PACS_transform(datasets, UTM=True)
- Transforming group location data into a path-adapted coordinate system
Using the spline-smoothed trajectory path of the group,
we get the distance of the individual to the group's spline path (left or right) as the X coordinate
we then find the distance along the spline path from the location of the groups center to the individual's location as the new Y coordinate
Developed by Dr. Eric Miller and James McIntyre for CABCS at Tufts University
Args:
datasets (list): list of dataset dfs to re-orient
UTM (bool, optional): True if UTM data, False if raw GPS. Defaults to True.
Returns:
oriented_datasets (list): list of PACS oriented datasets in dfs
- dp2s(t, sx, sy, x0, y0)
- Define the distance from point to spline
Args:
t (float): timepoint (normalized to 1 for spline)
sx (scipy.UnivariateSpline object): spline of x
sy (scipy.UnivariateSpline object): spline of y
x0 (float): x coordinate
y0 (float): y coordinate
Returns:
d (float): distance from point
g (float): gradient at point on spline
- force_converge(t0, args4d)
- Force the minimization function used to converge on the nearest spline point
iterate 100x before incrreasing (doubling) the tolerance
Args:
t0 (int): initial guess
args4d (list): packaged parameters for the distance calculation [x spline, y spline, x coord, y coord]
Returns:
rac (scipy.optimize._optimize.OptimizeResult object) : result of converged minimization problem
- plot_sample_PACS_figure(smooth_movements, ruck_slices_oriented, random=True, time_length=200)
- Plot a sample image for the PACS transformation
Args:
smooth_movements (list of DataFrames): list of smoothed movement period dataframes (not oriented)
ruck_slices_oriented (list of DataFrames): list of PACS oriented movement period dataframes
random (bool, optional): If True, choose a random movement period and random timepoint, otherwise use specified example timepoint. Defaults to True.
time_length (int, optional): length of time for the PACS to plot as a 2D histogram. Defaults to 200.
Returns:
None: None
- rotate(x, y, radians)
- rotates a point around the origin counterclockwise
Args:
x (float): original coordinate
y (float): original coordinate
radians (_type_): radians to be rotated
Returns:
tuple (float, float): rotated X and Y coordinates
