crop

Interactive data cropping tool.


Matlab & Octave

Y = crop(X)				% X is a sensor structure
        or
[Y,tcues] = crop(X,fs)			% X is a regularly sampled vector or matrix
	or
[Y,T,tcues] = crop(X,T)			% X is a regularly sampled vector or matrix

R

list <- crop(X)                         # X is a sensor list
       or 
list <- crop(X, sampling_rate)          # X is a regularly sampled vector of matrix
       or
list <- crop(X, T)                      # X is a regularly sampled vector or matrix         

Interactive data cropping tool. This function plots the input data # and allows the user to select start and end times for cropping.

Input var Description Units
X is a sensor structure/list, vector or matrix. X can be regularly or irregularly sampled data in any frame and unit.N/A
fs/sampling_rate is the sampling rate of X in Hz. This is only needed if X is not a sensor structure and X is regularly sampled. If X is not a sensor structure/list and X is not regularly sampled, T is a vector of sampling times for X. Hz
Output var Description Units
Y is a sensor structure/list, vector or matrix containing the cropped data segment. If the input is a sensor structure, the output will also be. The output has the same units, frame and sampling characteristics as the input.N/A
T is a vector of sampling times for Y. This is only returned if X is irregularly sampled and X is not a sensor structure. If X is a sensor structure, the sampling times are stored in the structure. Hz
tcues is a two-element vector containing the start and end time cue in seconds of the data segment kept, i.e., tcues = [start_time, end_time] (%Mat. or Oct.) tcues ← c(start_time, end_time) (#R).seconds

Matlab & Octave

load_nc('testset3')
Pc = crop(P);		% interactively select a section of data
plott(Pc)
% plot shows the cropped section

R

data <- beaked_whale
Pc <- crop(data$P)		#interactively select a section of data
Ydata <- list(depth = Pc$Y)
plott(Ydata)
#plot shows the cropped section
