Import data from a MAT file exported from Flydra softwareSource:
read_flydra_mat() is designed to import data from a
that has been exported from Flydra software. The resultant object is a tibble
that additionally has important metadata stored as attributes (see Details).
A file (or path to file) in .mat format, exported from Flydra
(Optional) identifier for this file. If not supplied, this defaults to
Name that will be assigned to the subject
The capture frame rate of the session
Additional arguments that may be passed from other pathviewr functions
A tibble with numerical data in columns. The first two columns will
have frame numbers and time (assumed to be in secs), respectively. Columns
3 through 5 will contain position data. Note that unlike the behavior of
read_motive_csv() this function produces "tidy" data that have
already been gathered into key-value pairs based on subject.

Other data import functions:
library(pathviewr) ## Import the example Flydra data included in the package flydra_data <- read_flydra_mat(system.file("extdata", "pathviewr_flydra_example_data.mat", package = 'pathviewr'), subject_name = "birdie_wooster") ## Names of variables in the resulting tibble names(flydra_data) #>  "frame" "time_sec" "subject" "position_length" #>  "position_width" "position_height" "velocity" "length_inst_vel" #>  "width_inst_vel" "height_inst_vel" ## A variety of metadata are stored as attributes. Of particular interest: attr(flydra_data, "pathviewr_steps") #>  "viewr" "renamed_tunnel" "gathered_tunnel"
